Properly define enterprise e-mail cloud

Over the past five years, cloud computing has become a good, bad effect, by not being recognized and now widely used. At the same time, IT companies have begun to notice that in order not to be eliminated in the industry, they must embrace the cloud and let the cloud change their existing state.

Cloud computing is very popular with customer applications, such as photo sharing, where the environment is quite different when it comes to corporate environments. Although corporate cloud is ideal for everyday applications, such as e-mail, because large enterprises have a different set of business, operational, security, and compliance needs, This does not necessarily mean that it is ready for an application like e-mail.

Public cloud solutions, such as Microsoft Office 365, provide companies with little or no technical infrastructure, and it is not possible for companies to directly control data, hardware, networks, operating systems, and other software. While this will attract policymakers to try to reduce complexity, it may not be suitable for larger companies that are subject to the stringent requirements of national security, control, storage or regulation. Public clouds, for example, are vulnerable to day-to-day operations and downtime, such as the well-known events that occur in Microsoft and Google.

Finally, the public cloud model includes hidden costs for plug-in options, such as archiving, migration, mobile device support, and increased network bandwidth. These can increase the total cost of ownership of private cloud options.

The fact is that cloud computing and convergence of data, voice, video and mobility have optimized the IT experience, such as email, collaboration and unified communications, and private cloud innovation. At the same time, a major reason for the IT debate is whether to raise most of the hardware and capital expenditures to the lowest common denominator of IT services, and to raise the concept of system management to a higher level.

Four cloud override options

According to many industry estimates, the public cloud mail market share is only 4%, five, the total number of data from SMEs (SMB). Companies have not yet jumped to the board. So far, the following 4 alternatives are more attractive to larger companies.

The first is the cloud-free computing model, also known as the traditional "internal" it option. Whether you believe it or not, this is the most common way for Microsoft's Exchange email, SharePoint, and Lync Unified Communications environment. In this case, the hardware, software, and data in your home can provide complete control, integration, and functionality. For many businesses, this solution (or a private cloud solution listed below) will probably be the most effective, at least until 2015, when Microsoft's 15 sets of products will become mainstream.

The most secure cloud model for e-mail is the private private cloud, which provides many of the same benefits as public cloud-public cloud sharing resources, hardware usage optimization, and flexibility-without service outages and other drawbacks.

This private cloud model is similar to the local option, but it is deployed on a Third-party data center, within a private framework, and connected to the private IP network of the enterprise, bypassing the MPLS or point-to-point VPN router/firewall.

For companies with strict security and compliance requirements, the private cloud's single tenant environment provides unparalleled privacy and protection. Workloads and infrastructure are easy to isolate, and process audit tools can be seamlessly integrated. Companies that contain data controls, hardware, networks, operating systems, and other software can even change the audit environment.

In fact, private private cloud provides more and more private cloud flexibility on the other hand, as the name suggests-the structure is actually focused on a secure, multi-tenant cloud computing. In this model, customers can quickly and easily deploy computers and storage resources as needed, using security, virtual hosts and built-in fault tolerance, complete infrastructure visibility. The choice of an enterprise to move into one of these private cloud models has a certain incentive to shift to a pure public cloud solution for the foreseeable future. This is due to all the key intangible assets such as feature set, control, cost and security factors.

Finally, the hybrid cloud, which combines the functionality of both public and private clouds, provides an incremental increase for entering the public cloud environment/long-term dual-model environment. It provides a great flexibility for unique business scenarios and/or security/regulatory constraints. For example, a business that runs an exchange premise may need a mail system running within another company. Instead of dismantling the existing infrastructure to use a new switching system, buy-out firms can simplify the company's employees by using Office 365, combining this public cloud service with existing internal e-mail systems. This hybrid approach provides revenue for public cloud e-mail, without inherent security, features, and control limitations.

Because of the relatively immature public cloud of many enterprise-critical applications, the hybrid cloud for most large companies holds more theory than the near-term alternatives. However, the potential benefits of a hybrid cloud deployment of a single application scenario (such as e-mail) and a mixed application environment, such as a public cloud incorporating Lync into a private cloud, becomes compelling.

Choose the right Cloud

For a high-level checklist, consider which of the following can be used to match the best technology and business needs of the enterprise:

Security: E-mail data is stored, what measures can be taken to protect its data from insiders and outsiders to steal, how quickly close to electronic discovery?

Availability: Adhere to a service level agreement (SLA) to ensure at least 99.999% uptime and provide compensation if SLAs are not met. This represents less than 6 seconds of downtime per week. By contrast, 99.9% of the SLA per year is up to a full working day downtime.

Support: Provide what type (phone, chat, email, etc.) support level (24X7,9-5, etc.). are support personnel outside the United States or the United States?

• Plugins: What is included in the basic email service? Secure filtering, archiving, encryption, archiving, etc. are they called add-on components?

• Migration: Will vendors help users move to new services, set up mailboxes, catalog integrations, and so on?

• Parity: Does all cloud versions provide the same level of e-mail functionality or do you need to make sacrifices for a complete set of features?

• Customization and control: Can the system be uniquely designed and configured to fit the needs of the business? Does the enterprise maintain direct control of data and systems?

• Integration: Are all Third-party applications plugged into e-mail still accessible in the cloud service?

With the advent of cloud computing, businesses provide the option to support e-mail services with a set of options. Each provides varying degrees of flexibility, control, availability, and practical/hands-off management patterns. Choosing the right cloud computing for corporate e-mail, any collaboration, and unified communications systems is best done through the unique features, benefits, and compromise mappings described above.
