New Data Center Engineering Technologies

 

Background of the Field 

Here at AFour Technologies we serve many customers who come from new data center technologies domain. 

Have developed solutions which provide visualization and monitoring for the data centers. 

We have expertise on working with data centers comprising of physical servers, virtualized and cloud-based environments. 

Problems Solved for our Customers 

Most of our customers’ business problems revolve around testing and QA services.

We provide end-to-end test consulting services including test strategy, designing, planning, estimation, execution, automation and setting up of end-to-end testing lifecycle models for the customers. 

Challenges faced by one of our customers: Customer was working on a new visualization and monitoring tool for data center technology. The key areas were to discover multiple appliances including physical, virtual and cloud-based infrastructure. 

They used different protocols to discover these appliances. But lacked a comprehensive testing solution for providing a bundle solution as a feature in their product. 

For providing a solution, we started with comprehensive analysis from testing prescriptive. 

Test strategy was sketched including functional as well as non-functional areas for their product. 

The functional areas covered all the aspects of their product features, functionalities and non-functional areas covered performance, security, reliability and scalability aspects of their product. 

Test strategy was developed consisting of 1000+ test cases with an automation-based approach; new feature was automated first, followed by execution through automation. 

100% regression through automation was achieved according to the test strategy.

New features and functionalities were covered manually and then converted into automation. 

With this approach test automation cycle was reduced significantly, while ensuring a timely delivery for all the release test cycles. 

Services we Provide 

At AFour, we provide 360-degree product engineering services that include development services, DevOps, QA, Testing, Consulting and Support Services. 

New Data Center Technologies at AFour: We typically focus on areas like storage, network virtualization and cloud. 

According to the storage-based requirements for datacenter-based products, we come up with storage specific test design and test strategies.

For deployment, configuration and upgradation of platform-based services, different virtualization platforms like VMware ESXi, Microsoft Hyper-V, and cloud-based services like OpenStack, AWS and Azure are used. 

Strategically, test beds are created according to the customer requirements, covering physical, virtual and cloud, for test and automation purpose. Then manual and automation tests are run on multiple test beds. 

We also manage infrastructure for customers rendering with different cloud service providers. A very niche area we work on is: To provide testing and automation services based on back-up and disaster recovery solutions. 

Team Composition          

Small Team: [2-3 Members] Consisting of a senior or a mid-level automation engineer, a test-development engineer, and a test lead who would provide comprehensive test planning and strategy services to the customer. 

Large Team: [8-10 Members] Consisting of a principal test engineer, a test architect overseeing the end-to-end test lifecycle management, and a combination of senior and junior test engineers highly specialized in automation using different open source technologies as well as scripting languages and comprehensive test execution services. 

Tools & Technologies 

At AFour, we have developed state of the art inhouse test automation frameworks and accelerators. 

Test accelerator like Vanilla with inbuilt libraries is used for accelerating test automation and development. 

We use UNIX based test framework called Booster. It is a multi-threading, multi-tenancy parallel test automation-based framework which allows users to automate test cases on the fly. 

Another framework is a headless browser test automation tool called Bolt. It doesn’t require a browser for running a test, the API based Bolt framework runs tests on headless browsers. 

Other than these technologies we have very comprehensive knowledge on different testing aspects in functional as well as non-functional areas: performance security and reliability. 

We are an expert at running regression tests through automation as well as functional tests which covers the high availability clustering solutions for different technologies including virtualization, hyperconvergence solutions, software defined storage and cloud platforms. 

We also cover the non-functional test areas for cloud platform as well and the DevOps integration using Jenkins for CI-CD integration, development and automation which runs seamlessly 24/7 on the given platform.
