Cloud-as-a-Service 2013 year in review

2013 was the year of a very advanced for cloud computing, one where the cloud models such as SaaS / PaaS / IaaS / DaaS / EaaS / or rather Everything-as-a-Service has emerged and accepted positively.

Today, demand for traditional hosting solutions decreasing, even if you announce a project and in case it does not appear in the term Cloud, eyebrows of many people will go up. In a few years, cloud computing with its new models of automatically resource consumption has established itself as a major trend in IT. But between tests, adoptions or marriages between more or less sensitive public cloud and private cloud, and ad effects, the reality of enterprise cloud remained questionable. read more

Everyone wants to be in the cloud

Cloud Computing

Since executives from Google and Microsoft talked about cloud computing in the first half of this year, it began a frantic race to see who is ahead with cloud computing services. All the great players that we know of already have their own cloud solution. And even with the brand name, they strategically designed and promoted their solutions to make their grip on market stronger.

  • Google App Engine
  • AT&T Synaptic Hosting
  • Elastra Elastic Cloud computing
  • eNlight Cloud services
  • HP, Intel and Yahoo – Cloud computing Test Bed – Consortium initially brings together Intel 6000 color processing

Microsoft itself announced their Windows Azure platform, on 27/10/2008 the version of the operating system for the new technology that seems to be the fad of the hour, but a strong trend. The Microsoft is offering its own structure to host third party. read more

OpenStack – a cloud management platform

OpenStack vs VMware

OpenStack is a cloud management platform which allows users to create virtual machines according to physical criteria (number of CPUs, amount of memory, disk storage etc.) and a base image that can provide the operating system and the most suitable software. It also has features volume demand (such as Amazon EBS) via Cinder (block storage), network on demand via quantum of cloud storage mode via Swift (a scalable redundant storage system).

Interoperability

As we all know OpenStack is based solely on open source tools: Linux, Libvirt, QEMU / KVM and is written in Python. It meets many standards ovf (open virtual machine format), qcow2 (to create a snapshot of existing files), EC2 or S3, and specific APIs (Nova). read more

Cloud computing – Is this the way the IT industry is headed?

cloud computing vs dedicated servers

Will cloud computing solutions replace the dedicated server hosting? Well this question you might have seen on many websites and it is obvious because everyone is talking about it as more companies’ even start-ups are using or willing to use cloud solutions. So is this the way the IT industry is headed?

In my personal opinion – NO

Most of the authors’ opinions are actually based on Gartner’s predictions; a leading technology research company. If you read articles based on their research you will see a massive amount of companies are shifting from dedicated servers to cloud computing. But there are certain applications and use cases that will require dedicated hardware for a while, for example banking systems. read more

Top Advantages of Cloud Server Hosting

There are various benefits that a business can experience when it moves to cloud computing. Here we list some of the major advantages that one can have by moving to the cloud.

1. Reduces Investment

When you have all your data on the cloud the need to maintain your own IT infrastructure is minimal. You can save a lot of money that would otherwise be spent on hardware, software and other equipments. The need for storage comes down to a minimum when you store most of your data on the cloud.

2. Low Cost of Operation read more

Cloud computing – sometimes yes, and sometimes no

Cloud-Computing

All studies and key informant interviews with countless suppliers and others demonstrated the phenomenon of cloud computing which is just out of the starting blocks, so sometimes hesitant, sometimes bewildering, but everyone agrees that it will profoundly change the way we use IT.

Ask ten people a definition of cloud computing and you will get ten different answers. Cloud computing is becoming a phenomenon in which many have not even passed the trend. In a recent European study by, it appeared that nearly 75% of companies are still not convinced of the usefulness of the cloud, while 17% see it is as a technology trend destined to a short life. A mere 11% believe it has an evolution in hosting which is durable. read more

Cloud Platforms: Open Source or Proprietary – Advantages and Disadvantages

Cloud Computing Platform

When it comes about choosing a software for Personal Computer systems, we know we can easily choose between a proprietary software and an open source. The same applies to cloud platforms: which model is best suitable for your business?

In today’s competitive market, cloud platforms like OpenStack, CloudStack and Eucalyptus are open source alternatives to proprietary solutions for commercial businesses.

These models provide many similar benefits that distinguish any open source program: community access, shared resources, rapid updates and freedom to not be tied to the limits of the software owners. But, although a few cloud service providers prefer to create their services on open source platforms, while most opt for the model of proprietary platforms. read more

What is Enterprise Cloud and Its Benefits to Enterprises?

I know that when I ask the question “What is Enterprise Cloud” some people might scoff. A fact that, all the cloud infrastructures and cloud service providers vary in various things and not all the methods can offer the same value as expected by the IT industry. Within the cloud arena, most of the people are aware of only three clouds – Public, Private and Hybrid which are well established. However, a new model known as “Enterprise Cloud” has taken place in the cloud arena.

Enterprise Cloud Hosting is much similar to the Private and Public clouds and offers the same advantages in terms of greater flexibility, instant provisioning of computing power as well as a virtualized and fully scalable environment. The same “private access” is provided by an Enterprise Cloud as you would get in a private cloud. These enterprise clouds are either controlled by an organization or a group of businesses. Similar to other deployment models of cloud, the services in the Enterprise cloud are delivered over the Internet, thus eliminating the need to buy hardware. The commercial grade components usually offer the usability, more features and greater uptime required by an organization. read more

Why Cloud Hosting is Essential For Your Business?

When you talk of cloud hosting you must picture your data with an external service provider. The cloud service provider takes care of your data and makes it available to you all the time and also undertakes the responsibility of securely storing the data and restricting access to the data.

Like every other business yours must also be having important data which are stored on the company’s computers and servers. However, storing data only on local computers might not always be advisable and may not be safe as well. There are various issues that are attached to handling data and ensuring it remains safe and accessible. For this purpose, it is essential that you consider having your data on cloud storage. Here are various reasons that make a cloud hosting solution something to look forward for storing your business data. read more
