Application builds when broken down into multiple smaller service components, are known as Microservices. When compared to the traditional Monolithic way, a Microservice Architecture treats each microservice as a standalone entity/module, essentially helping to ease the maintenance of its code and related infrastructure. Each microservice of an application can be written in a different technology stack, and further be deployed, optimized and managed independently.

Ballerina since v1.2.5 has built-in support for Azure Functions. In this way, you can take a Ballerina function and expose it as a serverless function in Azure Functions. Azure Functions take on a unique approach in defining serverless functions with the function trigger and bindings concept. In this way, we can access other cloud services such as storage services (queue, blob, etc.), CosmosDB, Twillio, and timers right from the function itself without any additional connectors or authentication processes. We map our parameters and return types with these bindings, which provides us direct access to the resources.

![](https://cdn.hackernoon.com/drafts/qvs32jg.png)
Ever since AWS made a serverless option of AWS RDS Aurora generally available, I’ve been on the edge of my seat, eagerly anticipating all the various possibilities. It would mean a breakthrough in building serverless architectures. No more managing connection pools with SQL. No more worrying about capping out available connections. This would make it viable to use serverless for database intensive operations.

As we know with great power comes great responsibility, on-demand backups are the real saviour if your Dynamo DB got corrupted abruptly. Also, it helps you to meet the compliance requirements for the ages if your client keeps bothering you like your Ex. But I don't have the tenacity to initiate the Backup every day. Hence, I devise a Serverless solution for all the lazy people like me out there to automate the DynamoDB backup. Where, we can explicitly mention the backup intervals, table names and backup retention period. I have achieved this using a conjunction of AWS services like Cloudformation, Lambda and Cloudwatch.

It goes without saying that if you want to orchestrate containers at this point, Kubernetes is what you use to do it. Sure, there may be a few Docker Swarm holdouts still around, but for the most part, K8s has cemented itself as the industry standard for container orchestration solutions. As Kubernetes matures, the tools that embody its landscape begin to mature along with it. One of the areas we have seen some optimization, in particular, is in cloud-native storage solutions.

The concept of a microservice perfectly fits the structure of a serverless function, which easily enables deployment and runtime isolation for different services. On the storage side, services such as DynamoDB also make it easier to have independent databases for each microservice and scale them independently (when required or desirable).

Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.

Buildah is a tool for building OCI-compatible images through a lower-level coreutils interface. Similar to Podman, Buildah doesn't depend on a daemon such as Docker or CRI-O, and it doesn't require root privileges. Buildah provides a command-line tool that replicates all the commands found in a Dockerfile. This allows you to issue Buildah commands from a scripting language such as Bash.

Since 2014 when AWS launched AWS Lambda and kickstarted the serverless movement, going serverless has grown exponentially for organizations of all sizes from one-man start-ups to huge listed global enterprises.

I have been using Lambda in production for about four years now personally, and three years professionally at Volta. Initially, I shipped Lambdas because it was easier than managing servers. At Volta, we now exclusively use server-less services because they are the smartest option for our workloads if we remember to support them correctly.
