Elastic Load Balancing handles the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones. It automatically distributes incoming application traffic across multiple targets, such as Lambda functions, IP addresses, containers, and Amazon EC2 instances.
ELB consists of three diverse types of load balancer which help to achieve extensive cloud computing measures. These include:
1. Highly available: Electric load balancing can route traffic to multiple targets automatically and can also load balance across a region routing towards a proper target in multiple availability zones.
2. Secure: The TLS settings can be centrally managed and one can even discharge the workloads of the CPU while working with Amazon Virtual Private Network Cloud providing sustainable security, user authentication, integrated certificate management, and SLS/TLS decryption.
3. Flexible: The applications could interact among each other through a microservice-based architecture and one can customize the application targets by the use of IP address in Elastic load balancer.
4. Elastic: It can manage rapid fluctuations in traffic and with the incorporation of auto-scaling, it can meet the various levels of measurable capacity with least manual involvement.
5. Hybrid load balancing: It is convenient to drift, switchover or migrate on-premises applications to the cloud since the elastic load balancer can balance load across AWS and on-premises using the same load balancer.
6. Robust monitoring and auditing: One can keep a track of activities of the applications, resolve the issues and know the cause of the problem by surveying the performance in real time with the assistance of Amazon CloudWatch metrics, logging and request tracing in Elastic load balancer.
1. Security: It uses Amazon Private Virtual Network Cloud thus providing extra security to the load balancers and one can even create an internal load balancer.
2. Health checks: It can track unfit targets and prohibits the flow of load towards and then balances the load towards the working targets.
3.TLS termination: With the help of SSL/TLS decryption and integrated certificate management, the CPU is offloaded and the SSL settings are managed at the core.
4. High availability: It can automatically distribute traffic to multiple availability zones or single availability zone working on the same load balancer.
5. Operational Monitoring: With Amazon CloudWatch metrics, logging and request tracking, one can overview the working in real-time.
6. Layer 4 and Layer 7 balancing: HTTP/HTTPS applications can be used to load balance for 7 Layer or strictly for layer 4 which depends on UDP and TCP controls.
7. Product Comparisons: Being flexible in nature, one can make choices on the basis of the need of the applications; such as one using an EC2-classic network can use a classic load balancer or if a flexible application is needed, one can use the Application load balancer.
