Cloud computing is being considered as the next big thing in the IT world, promising new levels of flexibility, cost savings and efficiency, especially in outsourced hosting, also known as IaaS. Cloud computing provides its users with services which they can access remotely from any location throughout the World Wide Web.

Linux, Apache Web Server and MySQL are some of the open source technologies brought forth by cloud computing. Over the years, open source has been one of the technologies being hyped by developers, but that has since moved to corporate IT. Nowadays, IT environments cannot operate without open source technologies. Open source has gained strong momentum today as it is being driven by and benefit from cloud computing technology.

Cloud computing market has been influenced by numerous projects launched in the recent past. Areas influenced the most include the development, setup and operations of cloud infrastructure, platforms and applications.

The following are some of the most important open source cloud computing technologies. The technology was assessed using the following criteria: the innovation and release velocity, the adoption rate of innovative users and developers and community development including support for large suppliers.


Some of the top five reasons for CIOs during their selection of open source cloud computing technologies include flexibility and openness. Standardization, on the other hand, has become more important and is one of the major drivers in the deployment of open source cloud technologies. Thus, OpenStack qualifies to be among the upcoming cloud infrastructure software.

Experts advise companies to develop modern and sustainable environments based on efficiency, reliability and openness principles. With this in mind, a stage for the implementation of multi-cloud and hybrid cloud infrastructure scenarios was set by CIOs.

This was to assist the IT departments to introduce and enforce holistic DevOps Services. DevOps plays a vital role in the PaaS adaptation processes and development of applications for the cloud. It also leads to improved speeds, which in turn improves the competitive edge of a business.

The following are some of the leading users who have put modern open source software into play to assist them in running their IT environments efficiently and as their way of becoming future oriented environments.

Cloud Foundry

Cloud Foundry is in the leading position when it comes to developing platform-as-a-service. Pivotal, a spin-off by EMC/VMware initialized the project. Organizations mostly use Cloud Foundry in hosted environments to deploy a private PaaS environment.

Also, MSPs uses Cloud Foundry when offering PaaS in a hosted environment. OpenStack and PaaS play a very crucial role in building highly-available and scalable PaaS platforms.


KVM, also known as Kernel-based Virtual Machine enjoys a high priority within the open source community. When it comes to infrastructure solutions like Open Source and openQRM, it is the preferred hypervisor. KVM represents cost efficiency, thus making it the best option to commercial offerings like Microsoft Hyper-V and the VMware ESX.

The market share of KVM stands at 12%, and because of this, it is used as the foundation for virtualization solutions by Red Hat. Currently, CIOs are looking for a cheaper solution to virtualize their infrastructure, and it is believed that the standard hypervisor KVM will be integrated with Openstack to achieve this.


Docker was the shooting star in 2016. The container technology is supported by major players like Google, AWS, and Microsoft and it is still gathering momentum. Docker came as a by-product during the development of PaaS dotCloud. It looks like a pure tool for developers at first glance.

Docker improves applications portability by enabling the movement of loosely joined applications that are found in containers. Many experts in the IT industry agree that Docker is a strategic tool for optimizing modern application deployments. Docker assists in increasing the portability of an application, increase availability and decrease risks.
