Stacked to Perfection

By Uchit Vyas

Over the years, IT infrastructure domain is moving from traditional way to IAAS (Infrastructure-As-A-Service). Many giant organizations have implemented IAAS based on OpenStack Cloud platform to build and run their native applications including infrastructure components like compute, storage, and networking. Rackspace and NASA are the pioneer contributors for OpenStack projects as NASA contributed their “Nebula” platform for compute resources and Rackspace contributed their “Cloud Files” for Object Storage.

Because of unique features of OpenStack making it very much adoptive and fast-evolving, Open Source project are known for their widely open platform based integrated solutions, user-friendly dashboards and flexibility.

OpenStack can fit with multiple environment based applications where it’s “dev” or “test” or “prod” environment because of its flexible components and simpler design. The core technologies beyond OpenStack combines an internally related projects with various parts including APIs, SDKs and CLIs for in-house or cloud environmental solutions and management of infrastructure. Moreover, almost all OpenStack APIs are extensible, that means you can keep compatibility with a core set of calls while giving access to more resources and innovating through API extensions endpoints.

The OpenStack project is widely adopted globally taking a collaborative approach of developers and cloud computing technologists. The OpenStack collaborative platform can be used for both public and private clouds.
Generally, if you may be working on an app or web based project and you are going to plan a vacation, or for simplicity let's say, building some new apartments in your area, or redesigning your trendy bungalow. In each of these, you will always need a mind-blowing strategy. A well-known Japanese military leader, Miyamoto Musashi, wrote the impressive statement—in The Book of Five Rings:

“In strategy, it is important to see distant things as if they were close and to take a distanced view of close things."

In recent times, Cloud and DevOps can be categorized in following categories in general:

  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)

Today, the most common issues persisting in the cloud world is to achieve agility, speed and service uptime up to 100%. All major data center solution provider companies are trying to become future ready next generation data center providers. Even in cloud, most of the public cloud vendors have expensive IT systems and have deployed over the years to achieve but in the next couple of years those systems will be out-of-date.

The major change for the new generation data centers have evolved the new model approach and adoption for the provisioning and deployment of new software and hardware. To handle the new age of cloud load, modern data centers have to enable multi-tenant model for scaling the approach. It is a huge step in the data center technology to shift the way of handling an entire infrastructure.

The next generation of Automation and DevOps for infrastructure has allowed system administrators and operators to deploy and deliver a fully automated infrastructure within a fraction of the time. The next generation data center and automation reduced the whole infrastructure components including storage, network, computing etc. as a single scalable and agile unit. So it's the administrator's responsibility to code the infrastructure as per environment requirements. To perform and adopt the next generation cloud mechanism where OpenStack comes as the ring-master here to support next generation data center Operating System. The ubiquitous influence of OpenStack has been felt by many global giant cloud enterprises like RackSpace, Red Hat, Cisco to name but a few. Nowadays most Cloud Services provider big giants run very large autoscaled private clouds based on OpenStack for their customers and internal units.
