Analysis of hybrid cloud architecture and the challenges it faces

Public cloud computing was once popular in the IT world. In the 2010, the industry's focus went to the private cloud after it people expressed concern about the security of the public cloud. At present, because everyone wants to require the flexibility of the operation, the hybrid cloud will naturally enter people's view.

The results of several recent cloud computing surveys have also confirmed the growing interest in mixed clouds. The Unisys survey, conducted in 2010, showed that 21% of IT organizations were looking at mixed clouds, and a survey by the Sand Hill Group in 2010 of more than 500 IT managers also showed that the use of mixed clouds would increase twice times over the next three years.

Architecture Analysis of Hybrid cloud

So what is a hybrid cloud? For starters, a hybrid cloud is a combination of at least one private cloud and one public cloud. A private cloud can be a private cloud within a company or a virtual private cloud located in an enterprise data center. As shown in the following illustration, we provide a simple, mixed cloud diagram, which includes a single enterprise internal private cloud and a single enterprise external public cloud:

The black circle in the figure represents an active virtual server mirror, while the white circle represents a virtual server mirror that has completed the migration with a secure connection. The arrows indicate the direction of the migration. Use a secure connection to connect the enterprise user to the cloud, where the secure connection can be either a virtual private network (VPN) or a secure HTTP browser.

In theory, a hybrid cloud can also include multiple private clouds and/or public clouds. The Enterprise data center in the diagram can include an Active server (whether virtual or physical) that is not part of a private cloud.

What is driving hybrid cloud computing?

Mixed clouds are generated in a seamless way to take advantage of both the public and private cloud. But some of the risks associated with public and private clouds also exist in mixed clouds. The benefits and risks of a public cloud, a private cloud, and a hybrid cloud are as follows:

Benefits of the public cloud:

Low investment barriers: paying for actual use

A good test/development environment for applications that extend to many servers

The risk of a public cloud:

Security issues: Multiple tenants and transmission over the Internet

It organizations may react negatively to the loss of data center functionality

Benefits of Private Cloud:

Since existing data centers are within control, there is no need to focus too much on security issues

It organizations retain control and management of data centers

Private Cloud Risk:

High investment risk for private cloud implementation and procurement of new hardware software

New business processes need to be developed;

Benefits of Mixed Cloud:

Operational flexibility: Running critical business on a private cloud, developing and testing on a public cloud

Resilience: High Peak and load tasks on public cloud

Risk of mixed cloud:

The hybrid cloud is still in the development phase and there are few products and services available

Security control between private cloud and public cloud; some of the concerns are the same as the public cloud

The challenge of mixed clouds

The challenge from Hybrid cloud computing is to provide cross-platform, cross cloud applications, and to maintain seamless operation of interfaces and cross management software. Users want to use data center tools to manage a mixed cloud environment. Ideally, they want to be able to create applications, or move existing applications between clouds in a mixed cloud environment without making any critical changes, such as network settings, security policies, business processes, or management/monitoring tools. This is a really difficult problem, because of the interoperability, mobility and other issues, as well as different APIs, tools, policies and processes, and so on, the mixed cloud tends to become more complex.

In the context of the hybrid cloud system, we will present the most prominent hybrid cloud on the market and determine the best use case for a hybrid cloud computing product.
