Elastic Load Balancing

-
Perks
-performance
-fault tolerance
-reliability



1) Multiple AZ - multiple instance
2) Single point of contact
3) Health Checks
4) Application -Classic

Needs: Listeners + ports


Classic Load Balancer has to be internet facing!


ALB : Targets(ec2) -> target group


Cross AZ LB - dispose load equally between instances

Routing Algoritms:
CLB - Round Robin
ALB - rule of routing

Helm Provenance and Integrity - https://github.com/technosophos/k8s-helm/blob/master/docs/provenance.md - Helm has provenance tools which help chart users verify the integrity and origin of a package. Using industry-standard tools based on PKI, GnuPG, and well-respected package managers, Helm can generate and verify signature files. a) Overview   -  I ntegrity is established by comparing a chart to a provenance record. Provenance records are stored in   provenance files , which are stored alongside a packaged chart. For example, if a chart is named   myapp-1.2.3.tgz , its provenance file will be   myapp-1.2.3.tgz.prov .  -  Provenance files are generated at packaging time ( helm package --sign ... ), and can be checked by multiple commands, notable   helm install --verify . b) The workflow This section describes a potential workflow for using provenance data effectively. Prerequisites: A valid PGP keyp...
