What is the hybrid cloud? Why is it important?

Cloud Computing: As organizations try to balance the need for on-premise computing with computing time and storage in the cloud, an intermediate solution has emerged: hybrid cloud computing.

For many years, IT decision-makers and corporate finance managers have been very interested in cloud computing, but the security-minded are reluctant to move their data and workloads into the cloud. Today, the underlying technology of cloud computing services is available for deployment within enterprises. So this is a new model that is taking hold in the company: the hybrid cloud.

What is the hybrid cloud?

The hybrid cloud is the combination of a public cloud provider (such as Amazon Web Services, Google Cloud or Joyent Compute) and a private cloud platform for use by a single company. The public and private cloud infrastructures, which operate independently of each other, communicate over an encrypted connection, using a technology that promotes the portability of data and applications.

The accuracy of this definition is important: public and private cloud environments in a hybrid cloud device are independent and distinct elements. This allows businesses to store protected or privileged data in a private cloud, while retaining the ability to leverage the public cloud computing resources to run applications that rely on that data. As a result, data exposure is kept to a minimum, because sensitive data is not retained in the long-term on the public cloud component.

It is important to understand that the hybrid cloud concept is not simply about connecting any server to a public cloud provider and labeling it as hybrid. The private infrastructure must run some form of cloud computing services, such as NemakiWare, an open source enterprise content management (ECM) software stack based on the interoperable CMIS standard, or Joyent SmartDataCenter, a platform form of cloud computing management for private and hybrid cloud deployments.

The benefits of a hybrid choice

One of the undeniable advantages of the hybrid cloud model is to have a private on-site infrastructure that is directly accessible, in other words, it is not provided via the public internet. Access time and latency are therefore significantly reduced compared to public cloud services. Given the imminent risk of consolidation of ISPs at the personal and professional levels in the United States, the current suspension of the net neutrality rule, and the torrents of threats between ISPs and service providers, this is an excessively high risk of reliance on the Internet, which is a single point of failure that can lead to the normal operation of an entire company.

Another benefit of a hybrid cloud model is the ability to have an on-premise IT infrastructure that can support the average workload for your business, while still retaining the ability to leverage the public cloud for disaster recovery situations. in which the workload exceeds the computing power of the private cloud component.

With the hybrid cloud computing model, IT decision makers have more control over public and private components than using a ready-made public cloud platform.

The corollary benefit is that you only pay extra computing time when these resources are required. As a result, for companies that have key events throughout the year and require significantly more computing time than normal (tax season, for example), using the public cloud is a cheaper alternative than the establishment of a private infrastructure that remains inactive most of the year.

In addition, setting up the private part of a hybrid cloud also leaves some flexibility in server design. It gives businesses the flexibility to set up fast archive storage at a cost certainly lower. Combined with the announcement of new 19-nm SSDs for servers and HGST’s 6TB helium hard drives, data storage (fast or slow) can be done without backup tapes.
