Handling large images has always been a pain in my side since I started writing code. Lately, it has started to have a huge impact on page speed and SEO ranking. If your website has poorly optimized images it won’t score well on Google Lighthouse. If it doesn’t score well, it won’t be on the first page of Google. That sucks.

![](https://cdn.hackernoon.com/images/yjr3zrq.jpg)
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.

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.

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).

![](https://cdn.hackernoon.com/drafts/9j1a3yra.png)
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.

When first looking into serverless migration and its architecture, it can feel like you’re staring down an endless shopping aisle of critical serverless tools that all need to be put into your basket straight away. Some services seem to offer the same function, while others can feel wildly different - both, as a result, can instill some doubts as to what is really necessary for your business and serverless application.

We discuss quite a bit about going serverless for SMEs and startups, however it’s often those with an already huge infrastructure, such as enterprises, that can find the move and change daunting. We see many companies from the likes of Coca-Cola to Netflix managing it but what does it look like in action? In this article, we share some best practices and insights on the serverless designs that can scale massively and represent enterprise models. For a real life example, you can also check out how Shamrock Trading Corp migrated to serverless from a traditional cluster - psst, they’re also giving away their winning strategy for a smooth transition.

While we know the many benefits of going serverless - reduced costs via pay-per-use pricing models, less operational burden/overhead, instant scalability, increased automation - the challenges are often not addressed as comprehensively. The understandable concerns over migrating can stop any architectural decisions and actions being made for fear of getting it wrong and not having the right resources. This article discusses the common concerns around going serverless and our advice to minimise their impact.
