Ephemeral vs Persistent Data Storage Patterns

  • Storage patterns available with lambda
    • Ephemeral Storage Patterns
    • Persistent Storage Patterns
  • Lambda is stateless
    • Functions are stateless, meaning that you can’t permanently store any data in the function(Example, session data, customer data, etc).
  • Lambda is Ephemeral
    • Not used for applications that need to run for longer than 15 minutes(Example, a database application or a web server That needs to stay up and running).
  • Persisting data
    • To persist data, The function must interact with a data store(Example save it to S3, EFS, Or Dynamo DB).

Effect : Deny vs No Action

No action allows us to provide granular level control over resources operations. For example, if we use effect, deny For all actions in IAM An, then we use effect allow over some actions in IAM then deniable supersede allow. The way to overcome above issue is to use NoAction on all IAM operations And action on Allowed IAM operations. Example { "Version" : "2012-10-17" , "Statement" : [ { "Effect" : "Allow" , "NotAction" : [ "iam:*" , "organizations:*" , "account:*" ], "Resource" : "*" }, { "Effect" : "Allow" , "Action" : [ "iam:CreateServiceLinkedRole" , "iam:DeleteServiceLinkedRole" , "iam:ListRoles" , "organizations:DescribeOrganization" , "account:ListRegions" ,

RDS is not server-less. Aurora surverless is seven less which is an exception. Dynamo DB is server-less. There are two types of backups for RDS Automated backups Database snapshots Read replicas Can be multi availability zones. Use to increase performance Must have backups turned on. Can be in different regions. Can be MySQL,PostgreSQL,Maria DB, Oracle, Aurora, SQL Server is not supported. Can be promoted to master, this will break read replica. Multi availability zone Used for DRG only and not performance. You can force a fail over from one availability zone to another by re-booting the RDS instance. Encryption at Rest Is supported for My SQL, Oracle, SQL server, Postgre SQL, Maria DB and Aurora. Encryp

Infrastructure Setup using Cloud Formation Templates

Services Required to create CICD Code Build Build code and deploy image in jfrog Code Pipeline Has (Continuous Integration Continuous Deployment)CICD flow Cloud Formation To deploy and create infrastructure we use yml files. S3 Store our data packages and yml files which are used by CFT. ECS To deploy our application on fargate servers We can also create our manual EC2 instances from pipeline. Secrets Manager Manages all the secrets. ELB/ALB Elastic/Application Load Balancer To map context paths of different services GitHub Stores our code Jfrog Used to store all the docker images Dockerfile Used to create a customised docker image Scanning for Vulnerabilities free code Sonarcube Checkmarx Twistlock Cloudwatch Used to store logs We create log group for each of instances Lambda Functions Used for serverless technologies. Creating a new Environment Create the YML images of the different resources required in the environment. The CFT templates are stored in S3 or can be uploaded from syst
