PowerCenter Cloud Edition, which became available on July 23, uses Amazon EC2, Amazon SimpleDB and Amazon S3 (storage) to provide access to enterprise data sources such as relational databases, flat files and SAAS (software-as-a-service)applications.
Bruce Cleveland: The SaaS Business Model and Some Common Legal Questions – worth a read. I believe these kind of issues is way underestimated.
David Linthicum: Will Cloud Computing kill the Datacenter?
Probably not. While cloud computing is a great fit for some applications, and/or other architectural components, it typically won’t be a fit for all applications and/or architectural components. There will always be some data, services, processes, and complete applications that you want to keep within your firewall for a number of reasons, including: Compliance, privacy, fear, control, and cost.
Brian Sommer: Is Your IT Shop Mature Enough for Cloud Computing?
CIOs will need to marry their needs and business requirements with the true capabilities of cloud capability providers. I suspect that some providers offer a cloud ‘space’ and not much else. CIOs will likely need more. They’ll want to work with providers that can advise them on needed capabilities in their application portfolio, changes they’ll need to make in their applications, techniques and technologies required to make cloud apps integrate with legacy apps, etc. If a cloud provider just offers bandwidth and disk storage, their solution may be woefully inadequate.
Yes, that´s what it boils down to. Just the “cloud space” is not that a big step from managed hosting of individual servers.
Joe McKendrick: Do we need cloud oriented architecture?
Absolutely. More than ever, as environments get quite complex if a multitude of services, both external with multiple providers plus internal retained have to be integrated.
He is linking to a post from ZAPLinks Ronald Schmelzer: Who’s Architecting the Cloud?
Given that too few cloud computing providers have your business in mind when they architect their solutions, and the ones that have a process-specific business model and approach aren’t concerned with your specific business, it lands upon the laps of enterprise architects within the organization to plan, manage, and govern their own architecture. Once again, the refrain is that SOA is not something you buy, but something you do. Perhaps we can start hearing the same mantra with cloud computing? Or will the cloud succumb to the same short-sighted, market pressure that doomed the ASP model and still plagues SaaS approaches? It’s not up to vendors to answer this question. It’s up to you… the enterprise architect. There are no short-cuts to EA.
