To do this, we navigatedContinue reading “Tuesday 12/28/21 Cloud Studies Update: AWS Architecture Evolution stage 1: part 2”

Adrian Cantrill’s SAA-C02 study course, 60 minutes: HA & Scaling section: [ADVANCED DEMO]: Architecture evolution, stage 1, part 1 [Advanced Demo] Architecture Evolution This was the first part of a seven part ‘advanced demo’. The purpose of this extended demo is to start from a single WP instance and evolve that into a scalable andContinue reading “Sunday 12/26/21 Cloud Studies Update: AWS Architecture Evolution stage 1: part 1”

Adrian Cantrill’s SAA-C02 study course, 60 minutes: HA & Scaling section: SSL Offload & Session Stickiness SSL Offload & Session Stickiness In this lesson we looked at two features of the Elastic Load Balancer series of products, SSL offload and session stickiness. For this lesson we focused on theory and architecture, as implementation is notContinue reading “Friday 12/24/21 Cloud Studies update: AWS SSL Offload & Session Stickiness”

Adrian Cantrill’s SAA-C02 study course, 45 minutes: HA & Scaling section: ASG Lifecycle Hooks, ASG HealthCheck Comparison: EC2 vs ELB ASG Lifecycle Hooks Lifecycle hooks allow you to configure custom actions which can occur during Auto Scaling group actions. You can define actions which occur either during instance launch transitions or instance terminate transitions. WhatContinue reading “Thursday 12/23/21 Cloud Studies Update: AWS ASG Lifecycle Hooks, ASG HealthCheck Comparison: EC2 vs ELB”

Adrian Cantrill’s SAA-C02 study course: HA & Scaling section: ASG Scaling Policies In this lesson we looked at auto scaling group scaling policies. To begin with, we learned that auto scaling groups don’t need scaling policies; they can have none and they work just fine. If there are no scaling policies, it just means andContinue reading “Wednesday 12/22/21 Cloud Studies Update: AWS ASG Scaling Policies”

Adrian Cantrill’s SAA-C02 study course, 40 minutes: HA and Scaling section: Applicaton Load Balancing (ALB) vs Network Load Balancing (NLB) Application and Network Load Balancer One important consideration is to know when to pick Application Load Balancers and when to pick Network Load Balancers. When using classic load balancers, you connected instances directly to theContinue reading “Tuesday 12/21/21 Cloud Studies Update: AWS NLB vs ALB”

Adrian Cantrill’s SAA-C02 study course, 75 minutes: HA and Scaling section: AWS Launch Configurations and Templates & Auto Scaling Groups Launch Configuration and Templates Launch Configuration and Launch Templates are two features of EC2. They both perform a similar function, but launch templates came after launch configurations and include extra features and capabilities. Launch configurationsContinue reading “Monday 12/20/21 Cloud Studies Update: AWS Launch Configurations and Templates & Auto Scaling Groups”
