What kind of cloud mode is more suitable? Briefly describe the pros and cons of several large private cloud manufacturers

The potential of cloud computing is huge, but it is also quite confusing. Some companies are doing their best to get into cloud computing, but more sophisticated IT companies are starting to look at the risks and rewards that cloud computing can bring. To save money and to make features, this is the survival of the economic downturn in the law. In the cloud computing market, there are more and more competitors in addition to the giants of IBM and Microsoft.

The current cloud computing solution is basically two: one is to extend the internal infrastructure to an external environment managed by IT professionals, and the second is to migrate the cloud to its own internal infrastructure.

The IT department's job is to build a secure operational process for data centers and systems that keeps it more reliable and manageable. It has always been the expectation of companies to spend more on cheaper prices to get higher utilization rates. So is IT department capable of mastering the essence of cloud computing and developing fast, real-time business support today? We need to rationally understand the various options and then more efficiently complete the company's deployment from the infrastructure to the cloud.

Current Private Cloud

The vendor defines a private cloud, and each vendor's definition is different. The number one reason to use a private cloud is automation and utilization. Companies are investing in virtualization from data centers because they want to save money by increasing the utilization of existing machines. The private cloud does this not only through virtualized servers, but also by assigning virtual machines to a pool of resources that can be allocated on demand with minimal action.

Standardization of Cloud Computing: the boom of outsourcing and the fall of brand

In fact, such a resource on demand model is also used by some vendors in the public cloud, this multi-tenant mode (multi-tenant model) can solve some security, usability and performance problems. Regardless of the definition of cloud computing, the goal is to improve the utilization of computing power and reduce the complexity of the management environment.

Vendor Evaluation: Amazon

Amazon launched the VPC (Virtual Private Cloud) last year. The concept of VPC is a private cloud that does not provide any internal IT framework for existing systems. VPC's approach is to host a portion of IT infrastructure in the cloud-a traditional and quite successful approach. VPC the internal network through a VPN, hosting the server instance on Amazon's EC2 (elastic Compute Cloud, resilient Cloud). Backup and SAN connectivity are implemented through its EBS (elastic block store, resilient Chunk storage), while monitoring is done via Amazon Cloudwatch. Creating virtual machines in the cloud, and adding them to the original path, embodies the flexibility of Amazon's cloud services. Use the Amazon Cloud service to preserve the subnets and schemas of the original network. Professionals can also create new EC2 instances directly using a custom image (similar to an internal virtual machine image) through the functionality provided by the AMI (Amazon Machine Images) in the S3 (Simple Storage Service). Separate EC2 instances are isolated between virtual firewalls and IPSec transport security.

Using Amazon Cloud Services does not involve upfront investment, but companies will lack control over these infrastructure (traditionally). In addition, the storage of sensitive information is also a concern, and professionals need to confirm that Amazon's managed solution meets the standards set by law. In addition, because the private cloud relies on a large area of VPN connectivity, transmission speeds are mostly slower than local data centers.

Vendor Evaluation: IBM

IBM's private cloud offerings are the first choice for most businesses with a private cloud service for households. Like most IBM products, businesses need to buy to use their cloud services. IBM typically customizes a solution for the enterprise's original internal infrastructure, and even hosts the cloud services with a large mainframe. The IBM consulting team will be involved in the process. IBM consultants are more focused on security and management, and the result is that most businesses have a cloud running inside the data center.

IBM's private cloud device is named Cloudburst. The solution is based on the system X BladeCenter platform, which is pre-loaded with the cloud computing framework.

Cloudburst is a way to implement a private cloud in a device way. Instead of taking full advantage of the existing cloud computing technology, the solution is to create a new infrastructure for image and schema deployment. The service provides a full cabinet with all the components that allow a "cloud" to run. This is a solution that can be configured according to requirements, so it can be perfectly integrated with WebSphere applications. Cloudburst allows you to create some quick macro templates and implement "Run once, multiple deployments" via the Web Replays feature.

Depending on the configuration, entry-level equipment is priced at 200,000 dollars.
