5 Things You Need to Know About Hybrid-Cloud Computing

Cloud computing is a relatively new trend in the Information Technology Industry. Because it is still a growing field, its precise definition is still a bit ambiguous. Generally speaking, cloud computing gives you the ability to deploy applications, systems and IT resources as services that reside in a global connected network known as the “cloud.” You can pull resources from the cloud whenever you need them, and you only pay for what you use.

A hybrid cloud is a cloud computing environment in which an organization provides and manages some resources in-house and has others provided externally. For example, an organization or company might use a public cloud service to store archived data but will continue to use in-house storage for operational data. Thus, let us look at the essential benefits of hybrid cloud solutions.

  1. Cost efficiency - Hybrid cloud computing can maximize cost efficiency, especially capital expenditure. A hybrid cloud gives companies the leverage of accessing IT resources without an initial capital investment. Because a hybrid cloud uses both private and public clouds, it allows users access to significant economies of scale without exposing too much of their important data and vital applications. Thus, cloud computing shifts a company’s IT investment from capital expenditure to an operational expense.
  2. Exit Strategy - Hybrid cloud computing can help a business build an exit strategy. One of the main concerns that companies have with a public cloud is the low level of data security. By using a hybrid cloud, businesses can maintain an in-house storage of operational data in their private clouds while using public clouds to store archived client information and data.
  3. Speed - When it comes to running your business, it’s all about efficiency and speed. The elastic and rapid nature of a hybrid cloud may be one of the best attributes that contribute to the success of running a business. There are services available through the hybrid cloud that are less expensive than maintaining in-house IT departments. A hybrid cloud strategy will make it easier to bring on new resources more quickly and efficiently.
  4. Stretch the Risk - From the perspective of cost, performance and rapid recovery, internally managed Disaster Recovery (DR) cannot touch the capabilities of a cloud or hybrid cloud system. Thus, using multiple providers to distribute the responsibility can help. Businesses can have one provider assume full responsibility, in case the other is compromised. This will give them the flexibility to switch to one from which they can operate efficiently post-disaster.
  5. Bidding - Your hybrid strategy can allow you to accomplish bidding deals with vendors, allowing you to manage service levels through competition. You set the criteria, and a pre-reviewed list of capable suppliers bid on the services you require according to the vendors own flexibility and asset availability.

Therefore, hybrid cloud computing can help your business function more efficiently, by decreasing risks and costs while providing more secure space for all of your business data.

How Virtualization Improves Your Company’s Security

Virtualization can offer many solutions and benefits to companies, but the issue of system security has always been an ominous cloud hanging over the ultimate decision of whether or not it is right for your business. Since the initial success of using virtualization as a tool for companies, security professionals have doubted the risk-reward ratio for implementing virtualization strategies to businesses. However, the truth is that virtualization technology actually has inherent security advantages. Some of those built-in virtualization security benefits include isolation, segmentation, and service insertion and chaining.

By default, virtual networks are separated from the underlying physical infrastructure of a network as well as other virtual networks. This principle of isolation is the foundation of most network security and one of the core features of network virtualization. Virtualization provides isolation for the physical network, meaning that any attacks on the virtual network will not compromise the underlying physical infrastructure.

Isolation also means that virtual networks operating on the same hypervisor (or virtual machine manager) can have overlapping IP addresses, which allows for isolated development, testing and production of virtual networks. Even though the term “isolated” may be misleading, the isolation feature simply means that virtual networks can work simultaneously with less security risks.

The idea of segmentation is similar to isolation, except in the case of segmentation, the isolation takes place on a smaller scale where different tiers within a multitier virtual network are segmented from each other. Virtualization offers the big advantage of built-in segmentation. Traditional methods of achieving network segmentation is extremely time-consuming and highly prone to security breaches due to human error. Since network segmentation is a core capability of network virtualization, the need for segmentation configuration and maintenance of the physical firewall is eliminated.

Insertion, Chaining & Steering
All of the fancy terms like “insertion”, “chaining” and “steering” really just mean one thing: easier implementation of more advanced, third-party security services. The many inherent security advantages of virtualization are not always sufficient means of IT protection for certain businesses. In many cases, clients will choose to leverage a more advanced, third-party security service to protect their company.

Despite this, virtualization can make adding those third-party security services easier and more effective due to the inherent ability to distribute and enforce those services throughout the virtual network. In other words, virtualization technology enables security services, like next-generation firewalls, to be available locally on every hypervisor (VMM) in the network.

The security benefits of virtualization, discussed here, are not a fully exhaustive list, as there are even more ways that virtualization technology can reinforce your company’s system security. Virtualization can secure IT systems on the server, network and desktop level, making it a common software solution for many companies.
