Cloud computing is touted as the wave of the future for IT, promising better economies of scale for its users. The IBM i has its share of service providers in this arena.
Cloud computing is aptly likened to a power grid, in which the electricity you use in your business or home isn't produced where you use it. Rather, it's produced at a central location and parceled out according to need, which you then pay for. Going hand in hand with virtualization, roughly defined as the ability to produce a fully functional replica of a computer system's hardware and software at a different location, cloud computing services are a rapidly growing industry.
While this industry is best known for providing centralized services for PC-based networks, the IBM i market now has a large and growing share of vendors offering cloud-based services. (If you're primarily interested in PC-based cloud services, information clearing houses such as Cloud Computing Companies.org can provide an overview of the largest and most popular providers.)
Some Basic Terminology
To provide a little background, server virtualization can include infrastructure and architecture design and maintenance, disaster recovery and high availability, server consolidation, and security management and compliance. Storage virtualization can include design, management, and implementation services; virtualization gateway analysis; and storage optimization. Cloud-based services and support can include virtual operations, storage and backup, and servers on demand.
Cloud services are further broken down conceptually into three types of offerings. Infrastructure as a Service (IaaS) offers virtual machines, and network utilities such as firewalls and storage, at a second location. Client companies can load operating systems and applications onto these virtual machines and access them via the Internet. Platform as a Service (PaaS) is this sort of service, with the service provider offering the OS, databases, and other software components that client companies can then use. Software as a Service (SaaS) adds the component of application software, offered and maintained by the service provider, which the client company can access remotely. In between are such measures as Storage as a Service (StaaS), which outsources backup services.
There are also three types of clouds: public, private, and hybrid. Simply put, cloud services offered by a remote service provider are a public cloud. Services offered within your own company for your own use is a private cloud. A hybrid cloud is when you outsource some cloud services, such as high availability (HA) and disaster recovery (DR), to an outside provider, and handle the rest of your cloud in-house.
Using cloud services is basically a financial decision. The major question to answer is whether the value to your enterprise of maintaining and controlling all your hardware and software in-house outweighs the value of being able to use your IT staff for other functions, such as data analysis, application development, or what have you, by outsourcing that control.
Asking the Experts
While it's beyond the scope of this article to get into cost-justifications that will clearly vary from one enterprise to another, some representative service vendors were willing to make some general statements.
"The economics are compelling," notes Dan Wilhelms, president of Symmetry Corporation, a cloud service provider for IBM i. "Our cloud solution costs 50 percent less than on-premise management."
"It comes down to arithmetic," maintains Bob Morici, director of Power Systems at Mainline Information Systems, "which varies with the amount of control the customer wants, what the customer can afford, and what's their return on that investment."
"It comes down to meeting a customer's needs," agrees Rich Waidmann, president and CEO of Connectria. "Certain applications are not well-suited to virtualization, so they need to remain running on a dedicated server platform. In some cases, clients have unique security or audit requirements, but they still want to enjoy the benefits of cloud computing."
Regardless of the financial considerations for individual companies, all three service providers unsurprisingly agree that the i is a good platform for cloud computing.
"It's a viable and outstanding cloud platform," asserts Wilhelms. "Its partitioning makes it easy to reallocate resources, and it's stable, robust, and mature."
"The i is well-positioned," Morici concurs. "Its inherent object-level security, database encryption, and the fact that security is part of its infrastructure are key. LPARs are good at keeping jobs separate, and by nature it's a multiuser platform."
Waidmann agrees in principle but also points out, "The application licensing is somewhat unique. IBM i software vendors typically look at the total processing capacity of the underlying servers when determining the price of their software. IBM and Connectria are working with ISVs to revise their pricing models to focus on the size of the cloud server, and not on the processing capability of the underlying servers within the cloud."
The Issue of Security
One area in which these three vendors didn't quite agree was on the issue of security. For example, when offered the scenario of service provider employees extracting confidential information, they expressed varying levels of caution.
"Cloud security concerns are overrated," maintains Wilhelms. "Many companies have more significant security issues with their own employees. One danger with emerging technologies is that analysts characterize things in ways that aren't helpful. Our clients have their own partitions, and each partition has the same security as a standalone server. We also use password-protected accounts, data, and so forth."
"Some have likened a public cloud to swimming in a cesspool," concedes Waidmann. "All our new employees are required to pass rigorous background checks prior to being hired, and we have extensive 24/7 monitoring and security measures in place to ensure that the data of our customers is protected. Using [our solutions] would be more equivalent to swimming at a private club with a limited membership of pre-screened businesses."
Morici was even more emphatic. "The i is good at keeping people out of each others' pockets. [The platform's] object orientation and strict control over work management, its limited pointer support, and our practice of not keeping data in contiguous files mean [our clients] are protected in their own job space. If you also do backups smartly by using encrypted backup tapes, I don't think [data thefts] can be done."
Getting Started with Cloud Services
When asked for advice on how to initiate cloud services, two of the service providers recommended using DR as an initial springboard.
"Start dabbling with DR," Wilhelms advises. "You can pay for just a sliver of steady state coverage that can be expanded to full coverage with a phone call in the event of a DR declaration."
"Doing DR/HA is easy," concurs Morici. "Then you can decide if hosting is a good next step or whether it's better to wait until next year. Any combination [of services] is possible."
To help you get started, below is a compilation of cloud providers that service the IBM i market. Included are application service providers that simply offer software on an SaaS basis. A partial listing of such companies can also be found in the MC Press Buyer's Guide and represents three varieties. Specialist ASPs provide a single application or a group of closely related ones. Vertical ASPs focus on applications for a specific vertical market. Enterprise ASPs provide a spectrum of applications useful for a wide range of businesses.
