In this blog, I am going to share some quick tips including Q/A and useful links from Day 6 of AWS Solution Architect Associate covering Module 5: Load Balancer, Route53 & AutoScaling. We also covered hands-on, Lab 18, Lab 21 out of our 30+ extensive labs.
On Day 5 session we have covered topics Amazon EC2, AWS Security Groups, EC2 Purchasing Options, Amazon Elastic File System (EFS)
On Day 4 session we have covered topics AWS Storage, CloudFront, AWS Snowball, AWS Storage Gateway.
On Day 3 session we have covered topics Identity & Access Management (IAM), AWS WAF, AWS Shield, AWS Key Management Service (KMS).
On Day 1 session we have covered topics Cloud Service Model, AWS Services, Create FREE Tier Account, Ways to Access Services
Load Balancer
A load balancer accepts incoming traffic from clients and routes requests to its registered targets (such as EC2 instances) in one or more Availability Zones. The load balancer also monitors the health of its registered targets and ensures that it routes traffic only to healthy targets.

Q1. What are the types of load balancers in AWS?
Ans. Following are the types of Load Balancers currently supported by AWS.
Q2. What does AWS use for Load Balancing?
Ans. Security. Elastic Load Balancing works with Amazon Virtual Private Cloud (VPC) to provide robust security features, including integrated certificate management, user-authentication, and SSL/TLS decryption.
Q3. What are the Benefits of Load Balancer?
Ans. Here are some of the key benefits of Load Balancer

AWS Global Accelerator
AWS Global Accelerator is a networking service that improves the performance of your users’ traffic by up to 60% using Amazon Web Services’ global network infrastructure. AWS Global Accelerator uses the vast, congestion-free AWS global network to route TCP and UDP traffic to a healthy application endpoint in the closest AWS Region to the user. If there’s an application failure, AWS Global Accelerator provides instant failover to the next best endpoint.
Q4. What are AWS Global Accelerator endpoints?
Ans. Endpoints in Global Accelerator can be Network Load Balancers, Application Load Balancers, Amazon EC2 instances, or Elastic IP addresses. You must create one of those resources first, and then you can add it as an endpoint in Global Accelerator. A resource must be valid and active when you add it as an endpoint.
Q5. What is AWS Global Accelerator vs CloudFront?
Ans. CloudFront uses Edge Locations to cache content while Global Accelerator uses Edge Locations to find an optimal pathway to the nearest regional endpoint. CloudFront is designed to handle HTTP protocol meanwhile Global Accelerator is best used for both HTTP and non-HTTP protocols such as TCP and UDP.

Auto-Scaling
AWS Auto Scaling lets you build scaling plans that automate how groups of different resources respond to changes in demand. You can optimize availability, costs, or a balance of both. AWS Auto Scaling automatically creates all of the scaling policies and sets targets for you based on your preference.

Q6. What is an auto-scaling instance?
Ans. Amazon EC2 Auto Scaling helps you maintain application availability and allows you to automatically add or remove EC2 instances according to conditions you define. Dynamic scaling responds to changing demand and predictive scaling automatically schedules the right number of EC2 instances based on predicted demand.
Q7. What are the Benefits of Auto Scaling?
Ans. Here are some of the Major Benefits
Q8. What is the Auto Scaling group & its policy?
Ans. An auto-scaling group is a collection of EC2 instances that your application can use to handle its workload. When you create an auto-scaling group, you specify how many instances are available to the group, and which metrics to monitor to determine the appropriate group size for any given application load.

AWS Route 53
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications by translating names like www.example.com into the numeric IP addresses like 192.0.2. that computers use to connect to each other. Amazon Route 53 is fully compliant with IPv6 as well.
Q9. Why is AWS DNS called Route 53?
Ans. AWS Route 53 takes its name with reference to Port 53, which handles DNS for both the TCP and UDP traffic requests; the term Route may signify the routing, or perhaps the popular highway naming convention.
Q10. What are the various Routing Policies in Route 53?
Ans. Following are the routing policies in Route 53
