Serverless Computing is a method of creating short lived on-demand compute resources, abstracted from their virtual and hardware requirements that come into existence at the point in time they are needed (from few milliseconds to 3 minutes maximum). Cloud computing has been a game changer in a number ways and the emergence of serverless computing/architectures is just another example of what cloud tech (and in particular AWS) has been able to achieve.
Serverless is about abstracting users away from servers, infrastructure, and having to deal with low-level configuration or the core operating system. By composing and combining different services together in a loose orchestration developers can now build complex systems very quickly and spend most of their time focusing on their core business problem. These serverless systems can scale, grow and evolve without developers or solution architects having to worry about remembering to patch that web server yet again.
Serverless computing resources must be able to start and stop rapidly. AWS Lambda removes the need to provision or manage any server. AWS Lambda only runs when needed and only consumes resources when running – pay only for the compute time you consume. Software WORX has implemented many AWS Lambda solutions, running virtually any type of application or backend services – with virtually zero administration. By uploading your code to the AWS Lambda eco-system takes care of everything else, including high availability and the instantiation of your Lambda function. Having integration with other AWS services Lambda functions can be simply triggered using a number of methods. SNS notifications through to S3 events and DynamoDB events can all be used to trigger your code.
When working with complex serverless implementations that involve multiple Lambda functions, SES, DynamoDB, S3, SQS, leverages frameworks like serverless, Zappa or chalice reduce some of the complexities in
Serverless computing can be more cost-efficient just in terms of computing resources, than renting or purchasing a fixed quantity of servers, which generally involves periods of underutilization or non-use. It can even be more cost-efficient than provisioning an autoscaling group because even autoscaling groups are typically designed to have underutilisation to allow time for new instances to start up. In addition, a serverless architecture means that developers and operations specialists do not need to spend time setting up and tuning auto scaling policies or systems; the cloud provider is responsible for ensuring that the capacity meets the demand.
With extensive experience in the Serverless marketplace, Software WORX can design and architect a Lambda solution for your business. From ETL and integration services through to full web based applications, Software WORX can design and develop SaaS or complex business applications to meet the needs of our clients.
