Simple Service Enterprise – part 4
Today we’ll take a REST from REST and I’ll touch upon one of the issues I ran into today: the two types of data there are. REST assured however that at least a few of the next posts will be about yesterday’s topic, as it has led to fierce debates here and there over the [...]
Simple Service Enterprise – part 3
My previous post showed the fundamentals of information interchange: exposing business functionality, currently encapsulated in the back-end, to the outside world via services. These services are a one-to-one translation to back-end functions, which are one-to-one translations to business process steps themselves: the smallest level of business transaction. I also showed that the How of exposing [...]
Simple Service Enterprise – part 2
Yesterday’s post was about Simple Service Enterprise, and showed the basics: to keep up with the growing diversity inside and outside your enterprise for getting the same functionality on different devices and platforms, you need an Integration layer (the red in the middle). Can’t argue with that, point-to-point integration is a neat quick and dirty [...]
Simple Service Enterprise – part 1
I plead for a Simple Service Enterprise. One that is ruled by Business, not IT. One that is interoperable with any other business, customer or consumer, regardless of the platforms they operate on. Regardless of the vendors that dominate those platforms. Regardless of the programming languages used on those platforms. Regardless of the devices used. [...]
80-20: the deadly cause of IT project failure
There seems to be a rush of IT failure topics these days, all trying to find the Holy Grail of project failure. While I hold that this is a world of AND and AND, not OR and OR, I do see a major cause for project failure for the last decade: shifting from serial processing [...]
Why SAP will be single-tenant at start
There’s an interesting discussion going on about multi-tenancy and SAP. Let me be clear on one thing: SaaS can’t be anything else but multi-tenant and opt-out, meaning that there is a single code base for all customers, with regular upgrades for everyone at the same time But what is only natural for SaaS “pure players” [...]
Will SaaS kill ERP? No, but it should
It’s been a busy few days. First a post on ZDNet by Eric Lai invented a few problems for Cloud, or rather SaaS, and especially multi-tenancy: inflexible, less secure, less powerfull and maybe more costly – is what Eric claims multi-tenancy SaaS to be. Thomas Wailgum neatly nailed that via a counterpost, as did Frank [...]
SAP, Integration and Star Trek: the future is now
I commented ranted on an SDN post yesterday. Submitting it failed, and I lost the +/- 500 words. A bit more miffed after that, I wrote the comment anew in Notepad, and copy/pasted that – it worked. I got a few reactions, some of which inviting me to post on the topic on SDN via [...]
SAP meets Cloud: something needs to vaporise first
I have been comfortably following SAP Influencer Summit 2011 from my chair, and reading up on the various posts and vids released throughout the process. It won’t surprise anyone that yesterday’s keywords were cloud, ByD, business, SAPonDemand and sales – thank you, you 350 participants who produced 1,500 tweets during the last day Many people [...]
Twitter needs a radical change of security NOW
I wrote a post a while back titled Your Twitter security is an egg, not an onion, explaining how Twitter only has one front door, like your house, and if you let people in, you let them in – after which they have access to everything, including your Direct Messages. A few months after that, [...]
Asphalt that controls traffic type and flow?
This weekend I attended the SAP Inside track NL event, held at Ciber HQ in Eindhoven. The event was great, and I really enjoyed it but would have loved to stay longer and gotten more involved. What has followed are great conversations and discussions, new people to follow on Twitter and elsewhere, and lots of [...]
High Availability From Non-High Availability: OpenStack, Dell, Crowbar, Private Clouds, and Moving the Enterprise Forward…
The Environment Recently a conversation came up about high availability in a traditional Enterprise Environment. Let me paint the picture for this environment; “This environment has several hundred servers, and several hundred applications. These application range in simple client server applications to n-tier applications strung across multiple services and machines. Some are resilient, some are [...]
Telotecture – architecture’s complement
Architecture – as I took 4 years of Greek it’s always meant the same word to me: that what stands at the beginning of construction, “ἀρχι-τέκτων”. Tekton is a builder / carpenter, and I was sure there was a verb tektein, but after looking for hours I’m afraid that this is it. At least arche [...]
Did Apple finally get hitched?
[Image by Roberta F.] Thanks to Peter Hicks for inspiring me for this title Lately I’ve noticed quite a few complaints regarding the upgrade to Apple’s iOS5. A few examples of that: the upgrade itself failing to complete, having to restore factory settings and lose all apps and files, battery draining like mad, Twitter failing [...]
Cloud API’s don’t exist, but become costlier over time
I had a discussion with George Reese on Cloud and API’s, starting with me saying I’d support a maximum of 3 different API versions, and off went the discussion. His “Max 3 versions? Do you hate your ecosystem?”, “What do you mean there’s no such thing as a public cloud API?” and “When you cease [...]
