Amazon Web Services Lambda

Image
  The AWS Lambda is a cloud service provided by Amazon, which is also known as ‘Lambda’ in short. It is a part of the Amazon Web Services and is also referred to as ‘serverless compute’. The word ‘serverless compute’ basically means the service doesn't explicitly require a server to run the code which is supplied by the developers. It runs without the interference from the developer in regard to managing the servers. The word ‘serverless’ might be misleading at times: - This doesn’t mean no server is required to run the code at all, it just means the developer need not worry about facilitating or managing the server. They could simply focus on writing high-quality, bug-free, well thought-about code, and all other requirements (such as providing infrastructure, resources, scaling, storage, server) required to successfully execute the code will be automatically taken care of by the Amazon Lambda service. Serverless also means the server doesn’t need to be running at all points in tim

AWS Shared Responsibility Model

Image
  AWS Shared Responsibility Model Security and Compliance is a shared responsibility between AWS and the customer. This shared model can help relieve the customer’s operational burden as AWS operates, manages and controls the components from the host operating system and virtualization layer down to the physical security of the facilities in which the service operates. The customer assumes responsibility and management of the guest operating system (including updates and security patches), other associated application software as well as the configuration of the AWS provided security group firewall. Customers should carefully consider the services they choose as their responsibilities vary depending on the services used, the integration of those services into their IT environment, and applicable laws and regulations. The nature of this shared responsibility also provides the flexibility and customer control that permits the deployment. As shown in the chart below, this differentiation

AWS Services - AWS Direct Connect

Image
  AWS Direct Connect: AWS Direct Connect links your internal network to an AWS Direct Connect location over a standard Ethernet fiber-optic cable. One end of the cable is connected to your router, the other to an AWS Direct Connect router. With this connection, you can create  virtual interfaces  directly to public AWS services (for example, to Amazon S3) or to Amazon VPC, bypassing internet service providers in your network path. An AWS Direct Connect location provides access to AWS in the Region with which it is associated. You can use a single connection in a public Region or AWS GovCloud (US) to access public AWS services in all other public Regions. The following diagram shows how AWS Direct Connect interfaces with your network. What is AWS Direct Connect? - AWS Direct Connect (amazon.com)

AWS Services - CloudFormation

  AWS CloudFormation: AWS CloudFormation is a service that helps you model and set up your AWS resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. You create a template that describes all the AWS resources that you want (like Amazon EC2 instances or Amazon RDS DB instances), and CloudFormation takes care of provisioning and configuring those resources for you. You don't need to individually create and configure AWS resources and figure out what's dependent on what; CloudFormation handles that. The following scenarios demonstrate how CloudFormation can help. Simplify infrastructure management For a scalable web application that also includes a backend database, you might use an Auto Scaling group, an Elastic Load Balancing load balancer, and an Amazon Relational Database Service database instance. You might use each individual service to provision these resources and after you create the resources, you w
