OpenStack – Its Open to all!

OpenStack is an array of tools for creating and handling cloud computing platforms for both- private and public cloud. It is a free platform having many groups of linked projects that enable processing storage and networking resources throughout a data centre. It is software and hence whoever wants to use it can easily do so by accessing the source code. This is supported by big companies as well as many individual cloud community members who believe in the concept of OpenStack and believe it is the next big thing in the near future. 

OpenStack is managed by the OpenStack Foundation, a non-profit which oversees both development and community-building around the project. It enables consumers to deploy VMs that can handle all cloud environment tasks from anywhere.

In a cloud environment, the consumer can compute from a remote location as the software runs as a service on a given sever rather than it being deployed on each user’s computer.

There are 9 major components that are identified by OpenStack community that bring up the core of this technology. These are available and officially maintained by the community at all times. They are listed below in brief:
Swift
Instead of storing data in the traditional ways by referring to locations on disk drives, Swift allows developers to refer to a unique identifier referring to the file or piece of information and let OpenStack decide where to store this information. This makes scaling easy, as developers don’t have the worry about the capacity on a single system behind the software.

Nova
Nova is the primary computing engine behind OpenStack. It is used for deploying and managing large numbers of virtual machines and other instances to handle computing tasks.

Cinder
Cinder is a block storage component, which is more analogous to the traditional notion of a computer being able to access specific locations on a disk drive.

Neutron
Neutron provides the networking capability for OpenStack. It helps to ensure that each of the components of an OpenStack deployment can communicate with one another quickly and efficiently.

Horizon
Horizon is the dashboard behind OpenStack. It is the only graphical interface to OpenStack. Developers can access all of the components of OpenStack individually through an application programming interface (API), but the dashboard provides system administrators a look at what is going on in the cloud, and to manage it as needed.
Keystone 
Keystone provides identity services for OpenStack. It is essentially a central list of all of the users of the OpenStack cloud, mapped against all of the services provided by the cloud which they have permission to use.

Glance 
Glance provides image services to OpenStack. In this case, "images" refers to images (or virtual copies) of hard disks. Glance allows these images to be used as templates when deploying new virtual machine instances.

Ceilometer 
Ceilometer provides telemetry services, which allow the cloud to provide billing services to individual users of the cloud. It also keeps a verifiable count of each user’s system usage of each of the various components of an OpenStack cloud.

Heat 
Heat is the orchestration component of OpenStack, which allows developers to store the requirements of a cloud application in a file that defines what resources are necessary for that application. In this way, it helps to manage the infrastructure needed for a cloud service to run.

Docker Ecosystem

Image
Introduction Docker is a new disruptive technology based on Linux containers. It uses Linux Kernel Containerization technology to create, secure and isolate independent containers to run within a single Linux instance. Due to this technology, a developer is assured that the application will run on any Linux machine without worrying about different customised settings. This is a revolution for applications created, shared & populated in the cloud. Docker – Its Significance   Docker has gained its popularity due to the fact that there is least dependency issues. Docker containers run almost everywhere. It can be deployed on containers, desktops, physical servers, virtual machines, into data centers, and up to public and private clouds. It provides a container for managing software workloads on shared infrastructure, while keeping them isolated from one another. Containers enable developers to design an application with all the essential parts and ...

IoT - Internet Of Things

Image
Definition IoT is known as data gathering, data analysis and action/task/computation with the help of network of various objects like computer, smartphone, hardware(sensors, controllers, converter), network. Wikipedia describes The Internet of Things (IoT) as the network of physical objects—devices, vehicles, buildings and other items embedded with electronics, software, sensors, and network connectivity— that enables these objects to collect and exchange data. The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems. Importance of IoT Today, we have lots of technologies available. We have computers, smartphones, internet (network), various hardware devices like sensors, controllers, converters, meters. But currently all these are used on individual level. But if one can imagine using all of these together, ...
