Employing All Layers of Cloud Computing

by

Often, when an enterprise initially embraces the cloud, they start off small. However, as they recognize the benefits of a cloud environment and get more comfortable using it, they go up the chain.

The starting point for most of the businesses is infrastructure as a service(IaaS). But IaaS isn’t all the cloud has to offer; to understand what possibilities really exist, it’s important to know what’s available.

There are two general categories of cloud services: cloud platform and cloud application.

Cloud Platform

The focus of cloud platform is based more on software for application development and hardware that optimizes IT resources. It is deployed by IaaS and platform as a service (PaaS).

With IaaS, an enterprise can rapidly build their IT infrastructure. It provides a flexible way to provision computing resources, like networks, storage, and processing. It can also include the maintenance costs for applications and any operating systems.

PaaS, on the other hand, is more focused on the development side, creating an environment in which the enterprise can use platforms, programming languages, and other tools for developing and managing their applications. This can include such things as testing, services for team collaboration, and application design.

Cloud Application

While cloud platform is comprised of IaaS and PaaS, cloud application is software as a service (SaaS) combined with business practices as a service (BPaaS). This allows for a multitenant software and business process delivery.

Enterprises using SaaS can use applications such as monitoring, collaboration, and customer relations management without having to go through a configuration process or install. Furthermore, the enterprise can see a leverage economy of scale due to the fact that SaaS is generally employed using a multitenant environment.

BPaaS further increases an enterprise’s cloud ability, allowing customers to use a web interface to interact with services or business outcomes. Often, this is used for human resources interaction and payroll processing.

By using SaaS or BPaaS, enterprises often find they can not only improve their efficiency and process but also reduce their overall operational cost.

The whole point of moving to the cloud is to be able to deliver the IT solutions a business needs in a dynamic and agile fashion. Using shared infrastructures and multitenant environments can drastically increase efficiency, reducing costs and providing better service without requiring as much maintenance.

Because using IaaS doesn’t give an enterprise all the benefits of the cloud, they should take a moment to look and see if they’re getting all the advantage of SaaS with their current system. If not, they should assess whether or not their cloud is large enough to support it.

Taking the next step and moving up the cloud chain can make a big difference, improving business overall.

Detecting and Eliminating the IT Shadow

by

A recent survey done by 2nd Watch found that more than 90 percent of business units in companies surveyed were using cloud services to conduct business. Some use it a lot; some use it less, but all are using it.

Ideally, they are getting their cloud services through the IT department. This allows the company to ensure availability, reliability, and security for the entire company. Unfortunately, this is not always the case. IT departments are hindered by aging infrastructure, tight budgets, and the inability to provision resources at a moment’s notice.

Shadow IT Emerges

When IT cannot provision resources fast enough for other departments, they will do it themselves. The growth of “shadow IT” is staggering. The same 2nd Watch survey found that more than 60 percent of business units using cloud services were bypassing IT completely to do so.

Shadow IT services may solve immediate problems for business units, but it causes many other problems for the company. Consider these:

  • It can increase costs for IT services since each business unit is doing its own thing. The company cannot leverage discounts by using a central provider.
  • Each department is developing its own island of data that is inaccessible to the rest of the company.
  • Linking the company’s IT infrastructure to unknown cloud services brings added security risks to the entire company.

Those are just a few reasons why it is imperative for companies to control shadow IT, but how can that happen?

Taking Control of Shadow IT

Most IT departments cannot respond fast enough to handle business units’ IT needs . That is what causes those units to bypass IT in the first place. What IT departments can do is to put a framework of governance and compliance in place, then to build a catalog of options for their business units.

The framework for governance and compliance sets out rules for business units that want to use cloud services. It outlines the acceptable architectures, and the minimum guidelines for reliability, availability, and security. This will not prevent the business units from procuring shadow IT in the cloud, but it will help protect the company from unnecessary risks. Enforcement of the framework must come from the C-level executives. The CIO needs to get commitment in the boardroom and then propagate it down the ladder.

After putting the framework in place and getting some level of compliance, the next step is to build a catalog of cloud services that meet your organization’s needs. When a business unit needs certain cloud services, they browse the catalog, choose the services they need, and send the request to IT. Because the infrastructure is in place, IT can quickly provision the services and get the business unit’s needs met with a quick turnaround time.

Building that catalog of cloud services cannot be done overnight. However, it needs to become a priority in companies where shadow IT is a growing problem.
