Why DevOps Should Own Their Databases and How To Do It

Aggregated on: 2024-03-07 15:27:13

DevOps is not new. Ideas to combine deployment and operations began to appear in the late 80s. It took us nearly 20 years to finally formulate the state of DevOps and begin the move towards DevOps engineers. However, we can’t stop here. While it may sound surprising, there is much more to be done than what we already did. Bringing deployments and operations together is just the first step, and we need to bring other areas together even more. Let’s see what exactly. What We Have and What We Lack We went through a big transformation in recent decades. We moved from monolithic applications to microservices. We deploy changes many times a day, and we use multiple platforms together.  The database complexity increased tremendously. We now have many databases, both SQL and NoSQL, and specific solutions for domains like machine learning. We can’t manage our databases the same way we did fifteen years ago. Even though we merged development and deployment, there are other aspects that we have disregarded until now. Some of them get bigger traction, such as DevSecOps (bringing security into the process) or ML Ops (bringing research and development together). However, we still lack good database ops solutions. Databases are still terra incognita for developers. They don’t manage them, they don’t optimize them, and they don’t know how to monitor and tune them efficiently. This is a gap that we need to address immediately. Read on to understand why.

Session Management in Distributed Databases

Aggregated on: 2024-03-05 18:12:13

Distributed databases partition the data across several nodes, spreading across regions depending on the database configuration. Such partitioning is fundamental to achieving scalability. All such cloud-native databases have some sort of a session management layer. A session, in plain terms, is the span of communication between a database client and server. It can span multiple transactions. I.e., in a given session, a client can do many writes and reads. The session management layer is usually responsible to guarantee “read your own writes”. I.e., data written by a user must be available for reading in the same session. Session Consistency In the distributed database world, with many regions serving the database, reads can happen from anywhere. There is fundamentally a need to distinguish between “Not Found” and “Not Available” scenarios. I.e. in the former case data does not exist while in the latter case data is yet to be seen by the region. This is important to provide “read your own write” guarantee. For example, let’s look at the time steps that happen in the below picture.

In modern application development, delivering personalized and controlled user experiences is paramount. This necessitates the ability to toggle features dynamically, enabling developers to adapt their applications in response to changing user needs and preferences.  Feature flags, also known as feature toggles, have emerged as a critical tool in achieving this flexibility. These flags empower developers to activate or deactivate specific functionalities based on various criteria such as user access, geographic location, or user behavior. React, a popular JavaScript framework known for its component-based architecture, is widely adopted in building user interfaces. Given its modular nature, React applications are particularly well-suited for integrating feature flags seamlessly.
