vpc2

 private subnet would not allow internet inbound traffic directly, but database has to connect internet and update the patches, todo so , you need to have NAT gateway(elasticip)


database server --> router--> internet gateway--> route tables says (nat-gateway-id) (for ip 00000/0)--then traffic goes to natgateway--> custom route table says (igw-id) it means allowed to go via internet gateway.



High performance 55000 sessions it is not possible only for ec2 instance directly.. without NAT


users cannot route traffic to a NAT gateway through a vpc peer,site to site vpn, or aws direct connect.

1. interface endpoints.. saas solution direct connect.

2. gateway endpoints



create vpc -- 
1publci subnet
  • 2. private subnte
3. public route table
4.private route table associate vpc, assign subnet.
5.internet gateway
6. natgate name it, then selecct in public subnet., associate elasitc ip, create natgw.
7. open publicroutetable, edit routes, add rount to internet 0.0.0.0/0 target igw 

8.select pvt routtable. edit add route --0.0.0.0/ nat gw in the target.


  1. 1. create vpc -- vpcname2
  2. 2. 10.101.10.16/ create vpc
  3. create internet gateway

Service Reliability Engineer (SRE): Primarily responsible for improving the reliability of services through collaboration with development, proactive monitoring, and optimization of redundancies in operations. SRE is an integral part of modern cloud development teams who are involved in proactive testing, observability, service reliability, and speed Shift left security – from DevOps to DevSecOps With a move from just a few releases a year to weekly feature releases, security can no longer be ensured manually. Security needs to be part of the DevOps pipeline and be automated. There are plenty of security tools out there from various vendors than can integrate with the pipeline. The key things to be addressed in a DevSecOps pipeline include security tools that address the following. Securing cloud-native development and operations Securing the DevOps pipeline involves catching security errors early in the cycle and addressing the vulnerabilities of deployable artifacts, as well as perfo...
