Amazon EC2 is service that provides scalable compute capacity in the cloud. In other words, the EC2 service of AWS gives us a virtual private machine in the cloud. COMPUTE capacity refers to the Power required to satisfy your workload in the cloud. This computer power given by EC2 service in terms of EC2 Instances is scalable and dynamic. If your workload requires a small computer power, let us Read more…

This database is very flexible as well as fast and is used for applications that have the necessity for consistency and latency at the rate of millisecond at any scale. Read More…

Elastic Load Balancer – ELB

Elastic Load Balancer distributes the incoming network traffic from application across different servers possibly could be different Availability Zones as well.

It helps and increases fault tolerance of your applications.

It serves a single point of contact for your clients ensuring that the application are available all the time.

You can either add of remove the instances from load balancer which does not affect your load balancer and so is the same deleting load balancer does not affect your Ec2’s.

It helps in scaling your load balancer’s traffic to your application as it keeps changing over time and also takes care of the majority of workload automatically as in when scaled.

Elastic load balancer has their own DNS names, they are never given any IP’s.

With DNS we can check how the load balancing activity takes place.

Health checks are mandatory to be set up on load balancers as they bring in the status of the load balancers.

It is basically the sanity checks that are tracked about the servers to report whether are healthy or unhealthy.

Main Health check responses set are:

Response time out:

When checking for an output it should bring in the status in scheduled time if no response it should at least throw the error message in allotted response time out.

Either an error or a response should be displayed in scheduled time.


The time taken to distribute load amongst the Instances.

Healthy Threshold:

Any output expected to be displayed within scheduled time also showing that servers are healthy enough to bring in the out managing the load.

Unhealthy Threshold:

If the instances are down or unresponsive or breached the threshold,load balancer will fail to manage the load.

Types of Elastic Load Balancing

Elastic Load Balancing supports three types of load balancers:

1.Classic Load Balancer.

2.Application Load Balancer.

3.Network Load Balancer.

Classic Load Balancer

Classic Load Balancer provides basic load balancing activity like any other load balancer across multiple EC2 instances.It works as per the Transport layer(4th layer) in OSI model.This was predominantly used before application load balancer was in place.

Application Load Balancers

Application Load Balancers works as per application layer(7th layer) of OSI model. Based on the application usage the loads are distributed and managed accordingly.

Network Load Balancer

Network Load Balancer is ideal for load balancing of TCP traffics. Targets could either be instances,containers,microservices etc.It can handle millions of requests per second at low latencies ensuring the network performance is high.

Key features in load balancer are:

  1. It ensures that high availability feature is in place, across multiple or single availability zone by distributing the incoming traffic.
  2. The request handling capacity is scaled up for in response to the incoming application traffics.
  3. Health check is one of the important features in ELB as it shows or brings in the status of servers. It ensures the sanity and status check of the servers.Ideally bringing in or detecting the health of Amazon EC2 instances.
  4. If any of the EC2 instances are found to be unhealthy,the load balancer routes the traffic to other servers rather than on the faulty or unhealthy servers or EC2 instances.
  5. Security features are enabled by adding security groups,NACL’s(Network Access control list) or even VPC(virtual private cloud) in load balancers.
  6. Load Balancer supports both IPv4 and IPv6 addresses
  7. Any metrics of load balancers are tracked by the monitoring or management tool called “Cloud Watch”.
  8. Logs retrieved from cloud watch for the same will help in diagnosing any application failures or web traffic..Load Balancer encryption is taken care by SSL secure socket layer) certificates, including public key authentication and offloading of SSL(secure socket layer) decryption from application instances.
  9. Load Balancing activity and Autoscaling services can be combined together to ensure the traffic’s are well managed and balanced ensuring the applications and services are in place.
