Editor's Note: Welcome to SmartAdvice, a weekly column by The Advisory Council (TAC), an advisory service firm. The feature answers three questions of core interest to you, ranging from leadership advice to enterprise strategies to how to deal with vendors. Submit questions directly to [email protected]
Question A: What service-level agreement provisions should we expect to be able to get on data center outsourcing?
Our advice: Data centers come in all shapes and sizes, and so do SLAs. With that in mind, the keys to establishing an SLA for a data center outsourcing project will include clearly defining the objectives and requirements; holding the service provider accountable for its work while also motivating it to stick to the agreement and meet deadlines; and monitoring the assessment metrics to ensure their fairness.
The data center exists for the sake of the business, not for the sake of technology. Therefore, the SLA must be based on the needs and expectations of the business user.
Data Center Outsourcing
Data center outsourcing enables internal resources to focus on high-value activities, and the organization on its core competencies. The SLA should ensure that this outcome isn't compromised. The most commonly encountered types of data center outsourcing include:
The typical benefits touted by data center outsourcing service providers include:
The primary drivers behind data center outsourcing are:
Data center outsourcing can positively affect a company's top line (e.g., through improved service on customer-facing applications) and bottom line, and could help it achieve industry best practices. The SLA should ensure that the best-practices objective is reinforced; therefore, a number of criteria should be included in data-center outsourcing SLAs, specifically:
General SLA Guidelines
Some useful guidelines to keep in mind when creating SLAs include:
With proper planning, a company can create a data center outsourcing SLA that will meet its organizational needs. Be clear about best- and worst-case scenarios and draft the SLA in partnership with the provider, emphasizing the processes that ensure that terms are being met and that service continually improves.
Our advice: What industry you're in may dictate how aggressively a company pursues RSS technology. Content aggregators and publishers are already using it heavily, but there are some open issues to be weighed.
Consider the purpose and reasons for your organization using RSS, and avoid jumping on any bandwagons. Educate your staff and your users about RSS' benefits and value. Evaluate opportunities--possibly start a blog--and understand the requirements for supporting it. Finally, plan accordingly.
RSS (variously defined as Rich Site Summary, RDF Site Summary, or Really Simple Syndication) is a method for delivering news or Web content from a syndicated source to subscribers, a multipurpose extensible metadata description and syndication format.
Although RSS has been around since 1999, multiple versions still exist, and some formats are unreadable by some tools. In addition, different groups supporting different versions each claim theirs to be the standard. Such confusion hasn't built either legitimacy or confidence amongst users. RSS readers (e.g., FeedDemon, Pluck, and NewsGator) are, for the most part, a separate component from the browser. We think that RSS readers should be part of the browser, such as in Mozilla's Firefox and Opera Software's browser.
Ever wonder what those orange-colored logos with the letters XML are on your favorite Web sites? They're links to RSS feeds: Subscribers automatically receive site updates because the publisher registered the site with an RSS aggregator and tagged RSS documents with XML codes that describe the type of document and where it resides.
RSS Is Not Push Technology
On the surface, RSS appears to resemble the push technology of vendors such as PointCast, but there are differences. Push technology was built on the broadcasting model, where providers fed content to desktops, accompanied by lots of ads; RSS places the choice of content in the hands of the user, aggregating the choice of readers.
For content providers and publishers, RSS provides an easy way to syndicate data. For browser vendors, it's a means for regaining control of the online experience. For consumers, it lets them better focus on content without being distracted by pop-ups and spam. This has some nicknaming RSS "the TiVo of the Web."

Our advice: Expect cultural challenges among the management and technical advisory staff, the technical support and operations staff, and among the software developers as they become acclimated to new roles and concepts.
Management Tips Be sensitive to the possibility of five pre-existing mindsets as they might affect the selection process:
Moving from MVS to anything else is called "downsizing." Both Unix and Windows have demonstrated the ability to handle huge and equivalent transactional loads.
Moving from MVS means compromising availability. In fact, non-MVS systems can be configured for absolute availability, by which we mean around-the-clock transaction processing for multiple consecutive years, capable of surviving fire, flood, or terrorist attack without loss of service and without data corruption. The team should be open to a collection of different technical approaches used to achieve this result, such as clustering, storage networks, and rolling upgrades.
Moving from MVS means compromising security. Unix and Windows systems have often been configured to make access as easy as possible, and therefore vulnerable to hackers. Properly managed versions of Unix and Windows can be kept as secure as MVS.
Unix is more virtuous, because it's open. Windows is just as open, if you define open as permitting easy porting of applications across multiple hardware vendors.
Linux is free. Cost must be computed for the whole environment, including middleware, security, and system-management applications, which make the cost of Linux comparable with other alternatives.
Be aware of potential concerns staff members may have about losing their status because Window is easier to use and maintain than MVS. There are still specialized technical skills required in a Unix or Windows data-center environment, so while many users know how to install Windows, not many people know how to configure complexes of Unix or Windows systems for absolute availability, nor how to design tight security or maintain portal servers. We recommend you tell the technical staff early on that they will not lose their status.
Software Developers' Concerns They will face several issues, such as a) approaches to the enhancement of the new applications, b) development speed, c) the extent to which users are empowered to program independently, and d) perception of the human interface. With those in mind, consider these:
