The innovation release are geared to give customers new features and enhancements that will be introduced into the next long term release. At the same time, these releases allow Oracle to set a road map of features that will drive the industry forward. The last major long term release was Oracle 11g (11.2.0.4), which has enabled businesses to run enterprise ready workloads for nearly fourteen years. Over this time, Oracle has released three innovation releases and one long term release(12.1, 12.2, 18.1, and 19.1) – with the long term release being Oracle 19.1. The long term release of Oracle 19c (19.1), there are a few dates that need to be kept in mind: Premier Support (PS) on April 30, 2024 + one year free support between May 1, 2024 through April 30, 2025 Error Correction Support (ECS) will be availiable through April 30, 2027 with paid support The image below shows what these release and support timelines look like currently: As previously mentioned, prior to 19c, the last long term release of Oracle 11g (11.2.0.4). This version of the Oracle database has served many organizations for over a decade leading Oracle to change their support strategy in 2021. This changed allowed organizations to continue running 11.2.0.4 until they could define plans to migrate to the next long term release (Oracle Database 19c). This “market driven support” extended the 11g (11.2.0.4) database until this year (2023). With the arrival of 2023, many organizations are finding themselves having to pivot quickly to upgrade to Oracle Database 19c (19.1.x). Many are doing this for two reasons: Financial Relief – lower support costs Migrate to a supported platform before evaluating where to go next Although these are two primary reasons for organizations to move, there is a third option that many tend to ignore. This would be the cloud strategy! With either of these options, it takes time to migrate between database versions and the migrations are not for the faint of heart… after all your business is running on these critical platforms.

Before data is eventually used it undergoes some form of data processing or transformation; including filtering, masking, and aggregations. The transformation process ensures data integration and standardization. This is particularly important when the destination for the raw data is a relational database. As the names suggests, data pipelines act as the “piping” or “plumbing” for many different projects in modern data platforms, data science projects, or business intelligence dashboards. Data is can be and often sourced through a wide variety of places – APIs, SQL, NoSQL, flat files, etc., but the data is not ready for immediate use. Preparation of data usually falls on the shoulders of data engineers or data scientist, who structure the data to meet the need of the business and the associated use cases. The type of data processing that a data pipeline requires is usually determined through a mix of exploratory data analysis and defined business requirements. Once the data has been appropriately filtered, merged, and summarized, it can then be stored and used. Well-organized data pipelines provide the foundation for a range of data projects; this can include exploratory data analyses, data visualizations, and machine learning tasks. Types of Pipelines There are a few different types of data pipelines, but two primary types stand out; which are batch processing and stream processing. Batch Processing The development of batch processing was critical step in building data infrastructures that were reliable and scalable in the early days. This type of processing enabled organizations to move and process large amounts of data into repositories at set time intervals, typically during off-peak hours. This way workloads were not impacted as batch processing jobs tend to work with large volumes of data; taxing the overall system. Batch processing is the optimal data pipleline when there isn’t a immediate need to analyze a specific dataset and is more associated with the Extract, Transform, and Load (ETL) data ingestion process. Streaming Data Streaming data is leveraged when it is required for data to be continuously updated. For example, apps or point of sale (POS) systems need real-time data to update inventory and sales history of their products; that way, sellers can inform consumers if a product is in stock or not. A single action, like a product sale, is considered an “event”, and related events, such as adding an item to checkout, are typically grouped together as a “topic” or “stream.” These events are then transported via messaging systems or message brokers, such as the open-source offering, Apache Kafka. Since data events are processed shortly after occurring, streaming processing systems have lower latency than batch systems, but aren’t considered as reliable as batch processing systems as messages can be unintentionally dropped or spend a long time in queue. Message brokers help to address this concern through acknowledgements, where a consumer confirms processing of the message to the broker to remove it from the queue. Architecture of Data Pipelines There are three phases that make of a data pipeline. Data Ingestion Data Transformation Data Storage Within these three phases, data is moved and transformed as needed to ensure data can be used by an organization. Data Ingestion: Data is collected from various data sources, including various data structures (i.e. structured and unstructured data). Businesses can choose to extract data only when they are ready to process it; however, it is best practice to land raw data with a cloud provider first (data warehouse or data lake). This way, business can update historical data if they need to make adjustments to data processing routines. Data Transformation: A series of jobs are executed to process data and transform the data into a format that is required by the destination data repository. Transformation jobs embed automation and governance into the process flow, ensuring that the data is cleaned and transformed accordingly. Data Storage: After data is transformed, the data is then stored within a data repository (commonly, a relational database), where it can be exposed to business stakeholders. Data Pipelines vs ETL Pipelines In many circles, the terms of “data pipeline” and “ETL pipeline” are often interchangeable within a conversation; however, the term “ETL pipeline” should be considered a sub-category of the conversation. Between these two terms of a pipeline, there are distinguished points that need to be understood. ETL Pipelines: follow a specific sequence. As ETL implies, the pipeline extracts data, transform data, and then loads the data into a data repository. Not all data pipelines follow this sequence of events. In fact, changing the order of the processes with an ETL pipeline enables an ELT (Extract, Load, Transform) pipeline. ELT pipelines have be come popular with cloud-native approaches since they do the transformation later in the process. ETL pipelines also tend to imply the use of “batch processing”, but as noted earlier can also be inclusive of stream processing. Data Pipelines: It is unlikely to see a true data pipeline undergo data transformations, like an ETL pipeline. Data pipelines tend to be more focused on feeding data to the end target platform (relational database, data lake, or data warehouse), where additional processes will be used to do the data transformation. Data Pipeline Use Cases With the term “big data” being coined in the 1990’s, the growth of data has continued to grow and projected to reach 180 zettabytes by 2025 (2 years from now). As this growth of data continues, data management and data cleaning becomes an ever-increasing priority and putting more pressure on the use of “data pipelines”. While data pipelines can serve many different functions, the following, broad applications of them within business are mostly seen: Exploratory Data Analysis (EDA): EDA is used by data scientists to analyze and investigate data sets and summarized the sets main characteristics, often employing data visualization methods – making easier for data scientists to discover patterns, spot anomalies, test hypothesis, or check assumptions. Data Visualizations: Representations of data via common graphics (charts, plots, info graphs, etc.). Data visualizations display information and communication of complex data relations and data-driven insights in a way that is easy to understand. Machine Learning (ML/AI): Machine Learning is a sub-branch of Artificial Intelligence (AI) and compute science which focuses on using data and models to imitate the way a human learns, thinks, and gradually improves it accuracy. Through the usage of statistical models, models are trained to make classifications or predictions, uncover key insights within an organization’s data. RheoData Recommendations In the above discussion on Data Pipelines, there is a lot for organizations to think about and how these pipelines may or may not be in place with your organization. Organizations are often looking at the bigger picture or the goal, but not how to transform their existing “pipelines” into more modern approaches of getting data where it is needed. For these reasons, RheoData recommends using the following Oracle products to establish or refresh “data pipelines” and building analytical or machine learning/artificial intelligence (ML/AI) processes today. Oracle GoldenGate / Oracle GoldenGate Service Oracle GoldenGate Steram Processing Oracle Autonomous Data Warehouse / Oracle Autonomous Transaction Processing MySQL Heatwave These products from Oracle can help organizations build robust data pipeline, scalable data lake or data warehouse platforms and ensure timely data processing.

This release of Oracle GoldenGate was produced to enable developers and small (under 20GB) production environments to build Oracle GoldenGate in an automated fashion – actually extending replication by building pipelines through a guided and automated process. This is nothing new other than the Product Management team has finally done something that was pushed for in 2018, a year after the Microservices architecture was released (in 2017). That was, build an end-to-end approach of setting up Oracle GoldenGate; enabling easier usage for the end-user! Sadly, from our understanding – the pipeline approach will not make it into the paid release of Oracle GoldenGate 23c and only in the “Free” release. What can Oracle GoldenGate “Free” be used for? This is a great question and was asked multiple times while at Oracle Cloud World last week. You can use Oracle GoldenGate “Free” in the following scenarios: As a development or test environment As a production environment – if your databases is 20GB or smaller As a training tool in a learning environment Note: Oracle GoldenGate “Free” is not supported by Oracle Support. For questions regarding Oracle GoldenGate “Free”, can be posted in the GoldenGate “Free” Community Forums. Note-1: RheoData offers support for Oracle GoldenGate “Free” to customers through our Tactical Assistance Program (TAP). Contact us today to get started (hello@rheodata.com) Limitations to Oracle GoldenGate “Free” Although Oracle GoldenGate 23c “Free” is free, there are limitations that needs to be reviewed and adhered to. These limitations are: Oracle-to-Oracle Only No more than 20GB in size For Container Databases (CDB), this includes the total size of all Pluggable Databases (PDBs) Oracle Database 23c Free is supported, with the exception of Parallel Replicats Support through community forums only*** Patches provided at Oracle’s descretion in the form of new builds in Oracle Container Registery Interaction with other GoldenGate “Free” instances only Oracle GoldenGate “Free” cannot be used with fully licensed Oracle GoldenGate products or other third-party integration tools. Integrated and Non-Integrated Replicats – ensure that you do not use Replicat-only features with licensed Extracts No Active Data Guard or XStream entitlements No Downstream capture support No support for Graph data types ***Refer to Note-1 for support information Note-2: Refrain from changing the Replicat type in the Oracle GoldenGate Microservices console, or making changes to the underlying parameter file. This will affect GoldenGate “Free”’s ability to manage the pipeline. This new option for Oracle GoldenGate is great for Small-to-Medium (SMB) who need a replication solution without breaking the budget. At the same time, enterprise customers can take advantage of this platform to enable developers in small scale development environments. Stay tuned, we will be providing more details on how this “Free” version of Oracle GoldenGate works.

The integrated extract that we rebuilt was stuck in a loop and displaying it was an initial load extract from the HTML5 page (AdminService). The adminclient (cmd line), said it was working fine. After the customer rebooted the their GoldenGate Service (GGS) environment, the integrated extract was still having problems. At this point, we executed an INFO EXTRACT , DETAIL and retrieved the sequence number (EXTSEQ) and the relative byte address (EXTRBA). With this information in hand, we removed the extract and the associated parameter file. After all, we were going to rebuilt the extract. The customer the rebuilt the extract using Microsoft VSCode with the RESTful plug-in (makes it really easy and scriptable). With the integrated extract rebuilt, we attempted to ALTER EXTRACT from the admin service, but there is no options (image 1). Image 1: alter extract no seqno/rba option This lead us to look at altering the extract from AdminClient within GGS. The alter extract command that we use was: adminclient> alter extract , extseq , extrba This command caused a syntax error. For anyone and myself, doing GoldenGate for better part of 15 plus years, this was odd. So, we went and looked up the documentation on ALTER EXTRACT in 19c (here). The command syntax for ALTER EXTRACT for Admin Client is clearly the same as any veteran to Oracle GoldenGate would remember. Admin Client Syntax (19c): ALTER EXTRACT group-name [, BEGIN (NOW | yyyy-mm-dd[ hh:mi:[ss[.cccccc]]]} | EXTSEQNO sequence-number [, EXTRBA archive-offset-number] [, ADD_EXTRACT_attribute] | SCN value] [, DESC [, UPGRADE INTEGRATED TRANLOG] [, DOWNGRADE INTEGRATED TRANLOG [THREADS number]] [, THREAD number] [, ETROLLOVER] [, ENCRYPTIONPROFILE encryption-profile-name ] [CRITICAL [ YES | NO ] [PROFILE profile-name | [AUTOSTART [ YES | NO ] [DELAY delay-number] [AUTORESTART [ YES | NO ]| [RETRIES retries-number ]| [WAITSECONDS wait-number ]| [RESETSECONDS reset-number ]| [DISABLEONFAILURE [ YES | NO ] ] ] ] Then we realized or remembered that we were using GoldenGate Service (GGS) and there might have been a few things different from the 19c release to the 21c release. After all, Oracle GoldenGate Service (GGS) is running on 21c. This prompted me to look at the 21c docs and I was sure it didn’t change; users needed a way to position an extract after rebuilding. The documentation for 21c (here) provide what the syntax is for ALTER EXTRACT in 21c – there are minor differences: Admin Client Syntax (21c): ALTER EXTRACT group-name [, BEGIN {NOW | yyyy-mm-dd[ hh:mi:[ss[.cccccc]]]} | [, EXTRBA archive-offset-number] [, ADD_EXTRACT_attribute] | SCN value] [, DESC [, THREAD number] [, ETROLLOVER] [, ENCRYPTIONPROFILE encryption-profile-name ] [CRITICAL [ YES | NO ] [PROFILE profile-name | [AUTOSTART [ YES | NO ] [DELAY delay-number] [AUTORESTART [ YES | NO ]| [RETRIES retries-number ]| [WAITSECONDS wait-number ]| [RESETSECONDS reset-number ]| [DISABLEONFAILURE [ YES | NO ] ] ] ] [, LOGNUM lognum] [, LOGPOS logpos] What this meant for the customer, is that the extract could be rebuilt; however, to find the correct position to start the extract from we needed to know how to get the correct System Change Number (SCN) or the correct Relative Byte Address (RBA). In discussions with the customer, we decided that it was best to use a known System Change Number (SCN). With the information we had, the customer knew we could go back an hour. From here, we used an old post which I wrote in 2014 on how to convert a timestamp to SCN (here). After the retrieving the SCN, we start the rebuilt extract as follows: adminclient> alter extract , scn The extract started successfully, remained on the correct trail file (we were over 660ish files) and captured data as expected. Lesson learned here was, between versions Oracle likes to change things and we need to keep up. At the same time, we wish subtle differences like this do not get over looked in the release notes.", "author" : { "@type" : "Person", "name" : "Bobby Curtis", "sameAs" : "", "url" : "https://rheodata.com/en-us/blog/author/bobby-curtis" }, "dateModified" : "10/11/2025", "datePublished" : "10/11/2025", "headline" : "Interesting change in ALTER EXTRACT command", "image" : { "@type" : "ImageObject", "height" : 400, "url" : "https://50642793.fs1.hubspotusercontent-na1.net/hubfs/50642793/Imported_Blog_Media/oraclegoldengateserviceALTEREXTRACT-2.png", "width" : 750 }, "mainEntityOfPage" : "https://rheodata.com/en-us/blog/alter-extract-command", "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://50642793.fs1.hubspotusercontent-na1.net/hubfs/50642793/RheoData%20-%20Logo%20-%20transparent-1.png" }, "name" : "RheoData", "url" : "rheodata.com" } } ``` ```json { "@context" : "http://schema.org", "@type" : "BlogPosting", "articleBody" : "Oracle’s Cloud Infrastructure (OCI) introduced the world to Autonomous Databases and a more automated way of thinking about managing your data.

Not performance issues. Not design flaws. Simple backup failures. The 3 AM Call That Changes Everything Picture this: Your phone rings at 3 AM. Production replicat REPPROD01 is down. The parameter file is corrupted. Your last backup? That shell script that supposedly ran last week but actually hasn’t worked since someone updated the directory structure two months ago. Your recovery options: Recreate from memory (good luck) Find that email from 6 months ago with “most” of the config Call the vendor for the 4-hour emergency support response By 7 AM, you’re updating your LinkedIn profile. The Secret: GoldenGate Backup Has Been Broken for Years Here’s what Oracle won’t tell you: GoldenGate has never had a proper backup solution. Sure, they gave us: GGSCI/AdminClient commands that dump configs (but where?) Manual copy scripts (that break constantly) “Best practices” documents (that nobody follows) New Configuration Services (limited to database and filesystem) – 23ai The result? 78% of GoldenGate shops have inadequate backup strategies. I know because I’ve audited dozens of them. Why Dual Strategy Isn’t Optional—It’s Survival Let’s talk about what actually saves careers: redundancy with intelligence. Local Backups: Your First Line of Defense Instant recovery when networks fail No dependencies on external systems Compressed .rdbin files that survive infrastructure changes Complete offline operation for air-gapped environments GitHub Integration: Your Version Control Lifeline Every change tracked with who, what, when Diff comparisons to see exactly what changed Branch protection for production configs Pull request workflows for change management Distributed copies across your team The Magic: When Both Work Together Production Issue at 3:47 AM ├── Local .rdbin available: Restore in 30 seconds ├── GitHub history shows: Last change 18 hours ago by jsmith ├── Diff reveals: Only checkpoint frequency modified └── Resolution: Config restored, issue identified, job saved Real-World Career Insurance Case Study: Financial Services Client Their senior DBA accidentally deleted all extract parameter files during a “cleanup.” The damage: 47 extract processes $2.3M per hour in transaction processing Compliance audit in 3 days Without Rewind: 16-hour recovery, $37M in losses, careers ended With Rewind: $ rewind --list —local $ rewind extract EXTPROD01 --recover --restore-path /dirprm # ... 46 more commands # Total recovery time: 4 minutes 32 seconds Stop Hand-Rolling Backup Scripts in 2025 I get it. You’ve got that bash script you’ve been maintaining since 2019. It mostly works. But let me ask you: Does it compress backups to save 60% storage? Does it integrate with your version control? Does it create restore-ready binary packages? Does it log every operation for compliance? Does it work offline when GitHub is down? Does it handle both source and target systems? If you answered “no” to any of these, you’re gambling with your career. CI/CD Integration: Set It and Forget It Here’s how Rewind becomes part of your pipeline, not another tool to manage: Jenkins Pipeline Example stage('Backup GoldenGate Configs') {   steps {       sh ‘’'           # Backup all production extracts           rewind extract EXTPROD01 —yes             rewind extract EXTPROD02 —yes           # Backup all production replicats           rewind replicat REPPROD01 —yes             rewind replicat REPPROD02 —yes           # Verify backups           rewind --list —local       ‘’'   }   post {       success {           echo 'GoldenGate configurations backed up successfully’       }       failure {           mail to: 'dba-team@company.com’,                subject: 'CRITICAL: GoldenGate Backup Failed’,                body: 'Immediate action required’       }   } } GitLab CI Example backup-goldengate: stage: backup script:   - rewind er --yes # Backup all extracts and replicats   - rewind --list -GH # Verify GitHub uploads only:   - schedules # Run hourly artifacts:   paths:     - *.rdbin”     expire_in: 30 days Kubernetes CronJob apiVersion: batch/v1 kind: CronJob metadata: name: goldengate-backup spec: schedule: 0 * * * * # Every hour jobTemplate:   spec:     template:       spec:         containers:         - name: rewind           image: rheodata/rewind:latest           command:           - /bin/sh           - -c             - rewind er --yes && rewind —list The Bottom Line Math Your current “strategy”: Manual backup time: 2 hours/week Script maintenance: 4 hours/month Recovery time when it fails: 4-8 hours Career risk: Catastrophic With Rewind: Automated backup time: 0 hours Maintenance: 0 hours Recovery time: < 5 minutes Career risk: Eliminated Cost: $4,900/year (or $408/month) That’s less than the hourly rate for emergency consulting when your homegrown scripts fail. Three DBAs Who Wish They Had Rewind The Architect who lost 6 months of optimization work when a SAN failure corrupted parameter files. No backups. Started fresh at a new company. The Team Lead whose junior admin ran a “cleanup script” that deleted production configs. Their backup script had been failing silently for weeks. LinkedIn shows “seeking opportunities.” The Consultant who assured the client their hand-rolled backup solution was “enterprise-grade.” Until it wasn’t. Reputation destroyed, contracts cancelled. Your Next Move You have three choices: Keep gambling with scripts and hope your number doesn’t come up Spend weeks building a half-baked solution that you’ll maintain forever Implement Rewind and sleep through the night Here’s my direct advice: Stop pretending parameter file backup isn’t critical. Stop believing your scripts are enough. Stop risking your career on 20-year-old practices. The DBAs who survive the next decade will be those who automated the basics and focused on strategic work. Backup isn’t strategic—it’s survival. Ready to safeguard your career? Start your 30-day trial: hello@rheodata.com Or keep rolling the dice.

Wither you are doing an general update or changing out your laptop, ssh keys need to be updated. In my case, I was changing laptops from Mac to Windows (not 100% sold on M1/M2 for consulting purposes … story for another time). When I went to interact with other OCI compute nodes that were previously built with OpenSSH key, I noticed I couldn’t get a connection to the compute instances. Leading to the need for changing the SSH keys on these nodes. Now can you change keys if you cannot access the node. Oracle provides some good details on making connections via Instance Console Connections, but I didn’t find this very helpful. Cool yes, helpful not really. This lead me to come up with a bit of a different approach for changing SSH keys – use a new compute instance and change the keys. What we needed to do was the following: 1. Dig out the old laptop and retrieve the OpenSSH keys that were previously used. Just need the private key. Email this to yourself or any other means of getting it over to the Windows machine. 2. Use PuttyGen and import the private key. 3. Once the key has been imported, it needs to be exported to force a new file format. If trying to use an older format, will lead to errors and other issues. 4. One the key is saved, it needs to be uploaded to the new compute node that will handle all the updating of the keys for other compute nodes. 5. Once the old RSA key has been uploaded to the new compute node, making SSH connections to the older nodes should be simple with the following command: $ ssh –i id_rsa2 opc@ The to use can be either the public or private address for the compute node. Since we were already connected to a node within the VCN, we opted for the private address. 6. From here, we needed to add the new authorized key to the ~/.ssh/authorized_keys file. After a few trail and error process, we found that it was easier to copy the private key and “echo” it into the authorized_keys file. $ echo >> authorized_keys Once the authorized_keys have been updated on the compute node, update the Putty configurations for the compute instance and connect to the instance. Now, that all our instances have been updated with the correct keys, the Compute Instance that was provisioned to just change keys can be removed. Oracle provides some great information within their documentation; however, we often find them a little bit difficult to follow. Seems like some of the steps are incomplete or missing something. Leading many to figure out creative ways of getting the same items done. Hopefully, this post will help you or someone else understand how to quickly change the SSH keys on compute nodes.

LLMOps, or Large Language Model Operations, refers to the set of practices and tools used to manage, streamline, and operationalize large language models. LLMOps is a cross between LLM and MLOps. LLMs – are a type of foundation model that cna perform a variety of NLP task, including generating and classifying texts, answering questions in a conversational manner and translating texts. MLOps – is a discipline that streamlines and automates the lifecycle of ML models. LLMOps applies MLOps principles and infrastructure to LLMs. Making LLMOps a subset of MLOps. The Need for LLMOps Wtih more and more Large Language Models (LLMs), like Cohere Command, OpenAI GPT-4, and many others, coming to market; they will require more resources and drive more complexity. Due to these reasons, they will require specialized techniques and infrasturcutre for their develoment, deployment, and maintenance. Below are some fo the challenges of operationalizing LLMs: Model Size and Complexity – LLMs are very large and complex models. This makes them difficult to train, fine-tune, and deploy. Data Requirements – LLMs require massive datasets of text and code to train. This can be a challenge to collect and curate. Infrastructure Requirements – LLMs require a lot of computational power and storage. This can be a challenge to provision and manage. Performance – Ensuring LLM performance at scale requires computational resources, time, and highly skilled professionals, which are not always available. Security and Privacy – LLMs can be used to generate sensitive text, such as personal information or creative content. It is important to implement security and privacy measures to protect this data. Interpretability – LLMs are often opaque and difficult to interpret. This can make it challenging to understand how they make decisions and to ensure that they are not biased. Ethical Considerations – LLMs may be subject to bias, toxicity, hallucinations, or other ethical concerns. It is important to implement guardrails to protect against these risks. LLMOps aim to address the challenges associated with managing LLMs and ensure they are efficient and effective for production environments. LLMOps help deploym applications with LLM models securely, efficently, and at scale! What is inclued with LLMOps? Key aspects of LLMOps are: Data Creation, Curation and Management – Organizing, storing, and preprocessing the large amounts of data required for training language models. This includes data versioning, ingestions, and data quality checks. Model Training – Implementing scalable and distributed training processes to train large language models. Includes techniques like parallel processing, distributed computing, and automated hyperparameter tuning. Model Deployment – Deploying large language models into production systems, often as APIs or services. Requires infrastructure setup, load balancing, scaling, and monitoring, to ensure reliable and efficient model serving. Monitoring and Maintenance – Ongoing monitoring of model performance, health, and resource usage. Includes tracking metrics, detecting anomalies and triggering alerts for prompt action. Regular model updates and retraining may also be part of the maintenance process. Security and Governance – Ensuring the security and privacy of large language models and their associated data. This includes access controls, encryption, compliance with regulatory requirements and ethical considerations like Responsible AI. CI/CD – Adopting CI-CD practices to automate the testing, validation, and deployment of LLMs. This enables faster iterations and reduces the risk of errors in production. Collaboration and Reproducibility – LLMOps emphasizes collaboration and reproducibility of LLMs. This includes version control, experiment tracking and documentation to enable collaboration among data scientists, engineers and researchers. Many of these key aspects are similar to MLOps. In LLMOps, they are extended and adjusted to meet the requirments of LLMs. LLMOps Landscape With the ever growing LLM landscape, LLMOps is constantly evolving, new tools and platforms are being developed to meet the needs of organizations. Here are a few: Open Source: Huggnig Face – a leading open-source software company that provides tools and libraries for build and using LLMs. MLRun – an open-source orchestration framework that can be used to operationalize LLMS. Enables scaling and automation of ML and LLM pipelines in a streamlined manner. Vendor Based (sampling): Microsoft – with the Azure platform, Microsoft has provided commercialized access to OpenAI’s LLMs and recently released Azure AI Studio to help develop, scale, and streamline LLMOps. Oracle – On the Oracle Cloud Infrastructure (OCI), has provided access to Cohere’s LLMs through the AI & Automation services. Access to LLMs is done through APIs and development in various languages.", "author" : { "@type" : "Person", "name" : "Bobby Curtis", "sameAs" : "", "url" : "https://rheodata.com/en-us/blog/author/bobby-curtis" }, "dateModified" : "10/11/2025", "datePublished" : "10/11/2025", "headline" : "What is LLMOps?", "image" : { "@type" : "ImageObject", "height" : 400, "url" : "https://50642793.fs1.hubspotusercontent-na1.net/hubfs/50642793/Imported_Blog_Media/LLMOps-What2Know-1-1024x560-1.png", "width" : 750 }, "mainEntityOfPage" : "https://rheodata.com/en-us/blog/what-is-llmops", "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://50642793.fs1.hubspotusercontent-na1.net/hubfs/50642793/RheoData%20-%20Logo%20-%20transparent-1.png" }, "name" : "RheoData", "url" : "rheodata.com" } } ```
