Today, cloud dominates in the IT world due to the many ways by which it has enabled businesses to solve their major IT concerns like cost, durability, flexibility, performance, security, operability, expertise, man effort, extendibility, scalability etc. The innovation of Cloud Computing and its associated technologies have revolutionized the IT world and most SMEs and almost all enterprises are heavily utilizing and harnessing the powers of cloud technologies.
A cloud based infrastructure is actually an ecosystem for your IT needs. It contains numerous components starting from the base hardware to the cloud software and then the analytics and monitoring tools. All these are integrated well and work in a pluggable architecture to provide you with capabilities for fault-proof computations, data storage and access, delivering services, development and deployment of your products etc. A good cloud infrastructure needs to have the crucial features of high availability, horizontal scalability in which your enhanced and growing IT and business requirements are met by adding up more logical resources rather than adding separate physical systems including hardware and computational platforms. Here is where the popular open source cloud softwareOpenStack helps you in achieving your goals. OpenStack helps in building your IT environment as Infrastructure as a Service (IaaS) that runs on commodity hardware and a number of component services on top of it that provides services for compute, storage, networking, dashboard etc. This service segregation into components is the key to achieving horizontal scalability with OpenStack.
Amazon AWS and EC2 are public cloud services implemented through an API driven infrastructure while OpenStack supports all private, public and hybrid cloud models through server based virtual machine technologies. According to AWS, Amazon EC2 is a web service that provides resizable compute capacity in the cloud and is designed to make web-scale cloud computing easier for developers. According to OpenStack, it controls large pools of compute, storage and networking resources throughout a data center, managed through a dashboard or through the OpenStack API. OpenStack works with popular enterprise and open source technologies making it ideal for heterogeneous infrastructure.
What is OpenStack?
OpenStack is an open source cloud computing platform that can be used to setup, control and manage various components of a cloud like the computing nodes, storage, database and networking resources through a web based administrative dashboard (Horizon). It provides the cloud platform service as an Infrastructure as a Service (IaaS) solution through a set of connected services. Users can provision resources quickly like adding new instances through the dashboard. OpenStack allows for achieving great horizontal scalability and is highly configurable. OpenStack can be effectively used to setup and deploy private, public and hybrid clouds. OpenStack is evolving continuously and has all the strengths and resources for the creation of highly available cloud platforms. It has revolutionized the cloud sector through the simplicity and flexibility by which businesses can setup their own private, public or hybrid clouds and utilize rapid provisioning for scalability.
Big Data refers to large volume of data and processes applied on these data for getting insights for better decision making and strategic planning. Big Data operations include data capturing, data storage, data sharing, data analysis, search, transfer, querying, projection etc. Modern Big Data concepts encompass predictive analytics, user behavior analytics etc. to extract value from data and use them for developing insights, products and services from the analysis. On the Big Data perspective, it’s not the amount of data but what businesses do with the data that matters. Big Data analysis helps businesses to find solutions for saving cost and time, development and implementation of new technologies, optimize product offerings, improve operational efficiencies, etc.
A production OpenStack deployment must need the following requirements in order to serve the business needs with performance and efficiency:
1. High availability of the service
3. Automated business and management operations
In a previous article, we have provided an Introduction to the OpenStack Technology, an overview of its architecture, service components and advantages. As we have specified, OpenStack is a cloud deployment and management system that allows administrators to control the cloud elements for computation, storage and networking and allows users to manage resource provisioning through the web interface. This article goes some more deep to explain the architecture and design guidelines for an OpenStack Cloud deployment that uses the Red Hat OpenStack platform to build a private or public IaaS cloud with Red Hat Enterprise Linux.
OpenStack is an open source project that consists of a set of software tools for building, deploying and managing cloud computing platforms for both private and public clouds. OpenStack is managed by the non-profit organization, OpenStack Foundation that promotes the global development, distribution and adoption of the OpenStack technology. It is supported and funded by a number of major enterprises, corporations and organizations and has thousands of community members world-wide who actively participate in technical contributions and community building efforts.
Enterprise data backup is a critical requirement for any business to secure its vital data resources. Although specific technology components like file servers, database servers, storage servers etc. have broad provisions for backing up and protecting data associated with them, these are on a component basis rather than on the global business level. The term “global business level” is used here to represent the data associated with all aspects and interests of any particular business, and is spread over the individual technology components. This includes data in file servers, databases, private or public storage spaces, system and application configurations for the desktops, laptops, mobile devices, network related hardware and software like router configuration, firewall settings and rules, data associated with online SaaS/IaaS/PaaS services like CRMs, Payment Gateways, Cloud Deployed data etc. Backing up and securing data associated with these global business aspects are therefore is a complex procedure and could not be fulfilled by the backup capabilities of any single component like database backup solutions that backups database data only.
