Handling multiple servers can be painful, especially in the short run. Multiple servers mean multiple developers who needs to work on the same code, making the code repository difficult to handle in the long run. One of the biggest disadvantages in the long run is the resiliency, which causes the whole back end a mess, making the website crash and slow down eventually.
AWS Lambda is a compute service that lets us run code without provisioning or managing servers. AWS Lambda executes our code only when needed and scales automatically, from a few requests per day to thousands per second. It is a pay as you go service and is a well-managed service hub. It allows us to get rid of over provisioning costs, as well as avoid the need of any boot time, patching, as well as load balancing. The best part is that we pay only for the compute time we consume - there is no charge when our code is not running. With AWS Lambda, we can run code virtually for any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale our code with high availability. We can set up our code to automatically trigger from other AWS services or call it directly from any web or mobile app.
Advantages of Lambda:
We can use AWS Lambda to execute code in response to triggers such as changes in data, shifts in system state, or actions by users. Lambda can be directly triggered by AWS services such as S3, DynamoDB, Kinesis, SNS, and CloudWatch, or it can be orchestrated into workflows by AWS Step Functions. This allows us to build a variety of real-time serverless data processing systems.
By combining AWS Lambda with other AWS services, we can build powerful web applications that automatically scale up and down and run in a highly available configuration across multiple data centers – with zero administrative effort required for scalability, back-ups or multi-data center redundancy.
AWS Lambda is a high-performance computing environment that not only eases developers’ workload but significantly reduces the cost of developing software or app. It works seamlessly in varied situations but should not be considered as a multipurpose service.
