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

Cloud Hosting Security

managed-cloud-hosting

With the Cloud now being seen as the defacto standard in enterprise computing, many are beginning to question the security of the environments provided and what steps have been taken to protect now just their servers, but also the data that they are hosting. Here we will look at what are some of the perceived threats to Cloud users and how the risk of these threats can be reduced.

User access levels

It is the responsibility of Cloud vendors to make sure that staff members are only assigned the access level to the environment that is necessary for them to perform their jobs, therefore preventing them from having access to information that could be classified and isn’t necessary for them to fulfill their roles.  This would mean providing support staff with access to the hardware infrastructure only, rather than with full administrator access that could offer them a way into Cloud VMs.  On occasions there have been attempts by staff members who have been provided with a level of access that goes well beyond their authority to access and steal data for personal gain, whether this is for the purpose of whistle blowing or selling private strategic documents to rivals.  In other situations where support employees have been assigned access levels well beyond what they require, inexperienced workers have made mistakes whilst performing specific tasks that have led to huge data loss and downtime.  In short, as a Cloud hosting provider you should ensure that employees are provided with the correct access because their actions, malicious or not, could end up damaging your business and brand as well as customer confidence. 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

An Insight On Web Application Cloud Hosting

cloud hosting, web applications

Many web developers are considering the thought of moving their applications from being based on the desktop to being web-based. This will enable then to work in synchronization with the cloud platform in order to offer the people with great experience and additional features. Web applications are generally complicated and they might require a number of servers for supporting the workload and user activities. This is where cloud hosting comes into the picture, it enables hosting of virtual machines as per the requirements. Through the cloud infrastructure, the load on the web applications can be distributed across various virtual machines in order to provide an efficient and stable hosting environment. 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 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

Dedicated Servers Or Cloud Servers – What To Choose?

The large volume of information that you must manage within the corporate structure pushes more and more data managers to turn to professional web hosting solutions. Unfortunately, the clarity of ideas about business requirements (increased bandwidth, flexibility in data management, advanced e-mail and so on) do not always correspond to equal clarity regarding the choice of services to be requested.

Because of the strong marketing action that affected the IT managers in recent years, we often tend to think that cloud computing services are the only answer to all your business issues. Promoted by industry researchers and analysts as the technology of the future, the “cloud” would seem to be just the one chosen by most of the companies. However, this belief does not always lead to success. Very often it happens that by focusing on the willingness to adopt advanced computer facilities, you do not make the correct assessments of the cost / benefit ratio. read more
