Introduction to ZooKeeper
The following article provides an outline for ZooKeeper Alternatives. ZooKeeper is a state-of-the-art Apache software that serves to maintain naming and configuration details and to offer flexible and robust synchronization across distributed systems, as a centralized service. It tracks the status of the cluster nodes of Kafka and also tracks the Kafka topics, scores, etc. ZooKeeper enables multiple clients to simultaneously read and write and act as a shared system configuration service. In the brain of the whole system, the ZooKeeper atomic broadcast protocol (ZAB), allows ZooKeeper to function as a nuclear broadcasting system and to provide orderly updates.
Various ZooKeeper Alternatives
Given below are the various ZooKeeper Alternatives:
1. Docker Hub
Docker Hub is the largest container images repository in the world, with a variety of content sources, including container community developers, open-source projects, and independent container software vendors. Users can have access to free public image storage and sharing repositories or choose the private repository subscription plan.
Traefik is the leading cloud-based load balancer and input control system in open source for HTTP and TCP applications, providing metrics and integrating all major cluster technology, with simple, dynamic, automatic, quick, full-function, proven manufacturing. Traefik Enterprise Edition has been built on top of Traefik and includes exclusive distributed features with high capacity for loading balance applications, security of authentication and encoding, and end-to-end monitoring and real-time tracking.
SkyDNS is a distributed advertising and detection service that is built on top of etc. DNS queries are used to discover services available. This is done with the use of DNS SRV records, with particular significance for subdomains, weights, and priorities. SkyDNS is a tool for the discovery of service. It uses several central servers that are highly consistent and tolerant of faults. Services to register nodes with an HTTP API, and HTTP or DNS queries to perform the discovery.
Hystrix is a latency and failure tolerance library which aims at isolating access points for remote systems, services, and libraries of third parties, preventing a failure to cascade, and providing resilience in complex systems that do not prevent failure. Hystrix’s a Netflix library. Hystrix isolates access points between services, prevents cascades, and provides retroactive options. For instance, it takes more time to send a reply when you call a 3rd party application.
5. AWS Cloud Map
AWS Cloud Map is a discovery service for cloud resources. Cloud Map allows you to set custom names for your application resources and keeps the dynamically changing resources up to date. As your web services always discover the most up-to-date locations of its resources, it enhances your application available.
By inspecting containers when they come online, Registrator automatically registers and deregisters the services of any Docker container. The Registerer supports registers for configurable services, which include consul etc and SkyDNS 2 at the moment.
7. AVI Vantage Platform
The AVI Vantage platform is based on the principles of software that allow a future generation of IT and business architecture to provide the flexibility and simplicity required. The AVI Vantage architecture separates data and control planes to provide load-balancing applications services, such as application analysis, auto-scaling predictive, micro-segmentation and auto-service for app owners in both on-site or cloud environments. The platform offers a centrally managed, dynamical pool of load-swing resources for the provision of granular services on commodity x85 servers, VMs, or containers.
RunC, a lightweight universal container execution time, is an Open Container Initiative (OCI) specification tool to spawn and run containers. This is the short version. This is short. The Long File: The governance scheme created for a common, standardized runtime specification by Red Hat, Docker, IBM, Google, Microsoft, and many other partners includes a readable specification document for the container’s runtime elements and a usable code-based implementation provided to Docker’s OCI. It includes libcontainer, the first library interface in the lower-layer, originally used on the docker engine, to build a container called the operating system.
CoreDNS is DNS software that is commonly used in containerized environments to support service discovery, particularly Kubernetes. The original 2016 version of the CoreDNS was written by Miek Gieben. In the past he had written a DNS server in Go language called SkyDNS and a popular DNS library called Go DNS. SkyDNS’ main purpose was to help service discovery, like its successor, CoreDNS. But Miek admired Caddy, a Go-based web server, and forced Caddy to create CoreDNS.
