IT Service—Software and Business Process Services

In this post, I explore software as a service (SaaS) and business process as a service (BPaaS). In the last post, I discussed IaaS, which provides infrastructure combined with services for use by a community of computer users. I also discussed platform services, which build upon IaaS and supply more support and software in a context like facilitating database processing or enabling software development. Platform services are very useful and in some cases provide the underpinning for SaaS or BPaaS. Let me explain.

Hot Response to the Future of DDS

Wow! Who knew so many people cared about the future of DDS!

We had certainly hoped for some comments - and indeed a number of people did comment. But more surprising were the number of tweets and LinkedIn references it generated. Clearly, it is subject that interested people and so we decided to continue the conversation in this week's blog.

OK, so it’s been a while since I wrote a blog. There are several related causes for this. Today’s blog will attempt to tie those causes together, and in the end, will explain where this blog will be headed for the next several entries – at least!

Authorization Checking During Auto Rebind

Last week I discussed the factors that cause a package to be marked invalid and go through AUTOREBIND. My recommendation was to always REBIND the package manually once the changes have been implemented.

Maxmizing IOPS

Recently I listened to a discussion of the differences in input/output operations per second (IOPS) in various workload scenarios. People talked about heavy reads. They talked about heavy writes. They debated whether it was better to use RAID5, RAID6 or RAID10. Things got a little heated.
