Virtualization is one of the core components of cloud computing, as it provides scalability and flexibility by enabling cloud service providers to emulate a hardware platform that is agnostic to both operating system and user workload to run different applications. The inherent security threats in virtualization include: communication blind spots, mixed trust level virtual machines, and inter virtual machine attacks.Read More
With the rapid expansion of cloud computing technology, the need for datacenter management has come into the spotlight. It is imperative that cloud service providers spend a great deal of time and resources reducing the carbon footprint on the environment, the energy consumption and improving power efficiency of the servers at the datacenters. The heat dissipation and energy consumption by these processors in the datacenters vary depending on the workloads of the applications running on them; however, the average datacenter consumes energy equivalent to 25,000 households. With increasing energy costs and reducing supply of renewable resources, the cloud service providers are always searching for ways to optimize the energy usage at their datacenters.Read More
Cloud computing providers offer three models as defined by the National Institute of Standards and Technology (NIST), which is a non-regulatory federal agency acting under the U.S Department of Commerce. Service models are defined as the final commodity delivered to a client based on the extent to which the cloud computing ecosystem is partitioned. The different types of service models are the SaaS (Software as a service), PaaS (Platform as a service) and IaaS (Infrastructure as a service) models.Read More
Cloud computing has given rise to a new paradigm of software application development. It provides the users with on-demand access to reconfigurable computational resources that can be provisioned rapidly with minimal manual intervention, giving users the power to develop any type of software application. Cloud computing is an amalgamation of various technologies such as virtualization, web services, inexpensive hardware and multi-tenancy. Organizations often move data to the cloud from their own data centers and vice versa. The movement of critical and sensitive data is often a cause of concern for organizations. The various models provided by the cloud service providers are interdependent and a security breach in one layer, like Platform as a Service (PaaS), will affect both Software as a Service (SaaS) and Infrastructure as a Service (IaaS) models.Read More
Cloud deployment models define the implementation of the cloud infrastructure within an organization. They are divided into four broad categories namely Private cloud, Public cloud, Community cloud and Hybrid cloud. Based on the needs of an organization, these implementations can help save capital cost and also eliminate the operating cost of these cloud infrastructures. The National Institute of Standards and Technology (NIST) define the framework of these models. The model defines the access to cloud infrastructure, the extent of which is defined by the service contract and the target audience of the cloud.Read More
A workflow is a sequence of steps involved in achieving a defined objective in any environment. These steps are in a certain order to improve execution and ensure efficiency. The end goal of a workflow defines the way the various tasks are structured, performed and tracked. The granular details such as: who performs these tasks, the order of the tasks, synchronization between jobs and flow of information required to assist the tasks, are also defined within the workflow.Read More
During the formative years of cloud computing technology, it mainly focused on the IT enablement of organizations. But, cloud computing is now playing a critical role in the rise of IT based economies, and offering unprecedented scalability. The National Institute of Standards and Technology (NIST) claims that the ease of scalability, customization and access to data anywhere and anytime has resulted in huge cost savings for many businesses. Additionally, the availability of resource pooling to enable software application development has contributed to its increased popularity.Read More
Over the last decade, the rapid expansion of cloud computing has only been possible through the key technological breakthroughs in related computing technologies. As a result, major changes can be seen in the way the four enablers of cloud computing technology - virtualization, multi-tenancy, web services and cost effective hardware—contribute to the development of effective and efficient cloud computing. These advancements have resulted in synergistic enablement, low cost, high speed, and scalable computing.Read More
In today’s technology driven world, cloud computing plays an ever-increasing role in our day-to-day lives. Without realizing it, we are connected to the cloud as part of our daily routine – like checking the fitness tracker after a morning run, accessing emails, shopping online, cloud backup, and watching movies online. The information delivery dashboards and interfaces we see on our smart phones or tablets, are the result of diverse applications working seamlessly together in the background to present requested information in a user friendly manner.
For accessing the cloud,Read More
There are many myths and assumptions concerning cloud deployment and on-premises systems. Before selecting the right option for data security, organizations must understand the truth behind these assumptions.
Some of the common myths are as follows:
- Private cloud is more flexible and meet the basic needs of clients;
- Private cloud is inexpensive option as compared to public cloud option;
- Private cloud is more secure and compliant when compared to the public cloud;
- Reliability and disaster recovery system of a private cloud is better than that of a public cloud;
- By selecting private cloud, organizations are given adequate scalability that is not possible through public cloud.
Let us discuss in details the reasons why companies choose public cloudRead More
