AWS Elastic Load Balancing (ELB) vs Zookeeper: What are the differences?

Key Differences between AWS Elastic Load Balancing (ELB) and Zookeeper

1. Elastic Load Balancing (ELB): AWS Elastic Load Balancing is a highly scalable and fully managed load balancing service provided by Amazon Web Services. It distributes incoming traffic among multiple EC2 instances, containers, or IP addresses, improving the availability and fault tolerance of applications.

2. Zookeeper: Apache Zookeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and group services in large distributed systems.

3. Scalability: ELB is designed to automatically scale its capacity as needed to handle traffic demands. It can handle millions of requests per second without any manual intervention. On the other hand, Zookeeper does not offer built-in scalability. Its architecture relies on a set of replicated servers, and scaling requires manual configuration and coordination.

4. Load Balancing Algorithms: ELB supports various load balancing algorithms, such as round-robin, least connections, and IP hash. These algorithms help distribute incoming traffic evenly across multiple targets. In contrast, Zookeeper does not provide load balancing algorithms as it is primarily focused on maintaining configuration information and providing synchronization services.

5. Fault Tolerance and High Availability: ELB provides fault tolerance and high availability by automatically spreading traffic across multiple availability zones and rerouting traffic in case of failures. It performs health checks on targets and directs traffic only to healthy targets. Zookeeper also offers fault tolerance through its replicated servers, ensuring data consistency and availability even in the event of server failures.

6. Use Cases: ELB is typically used in scenarios where there is a need to distribute incoming traffic to multiple backend targets, such as web applications, microservices, and API endpoints. Zookeeper, on the other hand, is primarily used for coordination, configuration management, and synchronization in distributed systems like Apache Kafka, Apache Hadoop, and Apache Storm.

In Summary, Elastic Load Balancing (ELB) is a fully managed load balancing service for scalable distribution of incoming traffic, while Zookeeper is a centralized service for maintaining configuration information and providing synchronization in distributed systems.

AWS Elastic Load Balancing (ELB)
AWS Elastic Load Balancing (ELB)

A centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications.

With Elastic Load Balancing, you can add and remove EC2 instances as your needs change without disrupting the overall flow of information. If one EC2 instance fails, Elastic Load Balancing automatically reroutes the traffic to the remaining running EC2 instances. If the failed EC2 instance is restored, Elastic Load Balancing restores the traffic to that instance. Elastic Load Balancing offers clients a single point of contact, and it can also serve as the first line of defense against attacks on your network. You can offload the work of encryption and decryption to Elastic Load Balancing, so your servers can focus on their main task.

-
Distribution of requests to Amazon EC2 instances (servers) in multiple Availability Zones so that the risk of overloading one single instance is minimized. And if an entire Availability Zone goes offline, Elastic Load Balancing routes traffic to instances in other Availability Zones.;Continuous monitoring of the health of Amazon EC2 instances registered with the load balancer so that requests are sent only to the healthy instances. If an instance becomes unhealthy, Elastic Load Balancing stops sending traffic to that instance and spreads the load across the remaining healthy instances.;Support for end-to-end traffic encryption on those networks that use secure (HTTPS/SSL) connections.;The ability to take over the encryption and decryption work from the Amazon EC2 instances, and manage it centrally on the load balancer.;Support for the sticky session feature, which is the ability to "stick" user sessions to specific Amazon EC2 instances.;Association of the load balancer with your domain name. Because the load balancer is the only computer that is exposed to the Internet, you don’t have to create and manage public domain names for the instances that the load balancer manages. You can point the instance's domain records at the load balancer instead and scale as needed (either adding or removing capacity) without having to update the records with each scaling activity.;When used in an Amazon Virtual Private Cloud (Amazon VPC), support for creation and management of security groups associated with your load balancer to provide additional networking and security options.;Supports use of both the Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6).

What are some alternatives to Zookeeper, AWS Elastic Load Balancing (ELB)?

HAProxy

HAProxy

HAProxy (High Availability Proxy) is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications.

Consul

Consul

Consul is a tool for service discovery and configuration. Consul is distributed, highly available, and extremely scalable.

Traefik

Traefik

A modern HTTP reverse proxy and load balancer that makes deploying microservices easy. Traefik integrates with your existing infrastructure components and configures itself automatically and dynamically.

Eureka

Eureka

Eureka is a REST (Representational State Transfer) based service that is primarily used in the AWS cloud for locating services for the purpose of load balancing and failover of middle-tier servers.

etcd

etcd

etcd is a distributed key value store that provides a reliable way to store data across a cluster of machines. It’s open-source and available on GitHub. etcd gracefully handles master elections during network partitions and will tolerate machine failure, including the master.

Fly

Fly

Deploy apps through our global load balancer with minimal shenanigans. All Fly-enabled applications get free SSL certificates, accept traffic through our global network of datacenters, and encrypt all traffic from visitors through to application servers.

Envoy

Envoy

Originally built at Lyft, Envoy is a high performance C++ distributed proxy designed for single services and applications, as well as a communication bus and “universal data plane” designed for large microservice “service mesh” architectures.

Keepalived

Keepalived

The main goal of this project is to provide simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures.

Hipache

Hipache

Hipache is a distributed proxy designed to route high volumes of http and websocket traffic to unusually large numbers of virtual hosts, in a highly dynamic topology where backends are added and removed several times per second. It is particularly well-suited for PaaS (platform-as-a-service) and other environments that are both business-critical and multi-tenant.

node-http-proxy

node-http-proxy

node-http-proxy is an HTTP programmable proxying library that supports websockets. It is suitable for implementing components such as proxies and load balancers.
