  • Infrastructure Integration includes networks, servers, app servers, data bases, web servers, and in my mind, even application installation. These are well defined, usually have their own staff… and they take up a large part of budget/effort, but because they are visible, for the most part, they are accounted for (time-wise). Unfortunately, as we all know, this is just the “setup”… next, you have the magic… The magic of DATA integration
  • This is the POINT behind all the infrastructure integration efforts. If not for teasing out information about our data in a way that’s usable, we wouldn’t do any of the other stuff. The other stuff is just necessary evil. It’s the boat ride you have to take to the dive site… it might make you queasy, but you can deal with it because once you get there, you’ll see some neat stuff.
  • It’s Data integration that’s hard (and expensive). And, importantly, it’s hard to explain to others, so they discount it.
  • This is really less of a definition, and more of putting an edge around a concept. And, that edge doesn’t fully surround the concept, only it gives it some shape.
  • This is not really a definition, but it does help keep our eyes on the prize and measure the success we have with it. I prefer to think of it as…
  • Of course, I’ve still not defined anything. Just trying to put some parameters around it. I defined integration earlier, now I’m saying turn commodity integration (defined as necessary, but not differentiating) into a utility.
  • Talk about thinking outside the box. If email is commodity, everything below it in the infrastructure stack is too. And, of course, this is a great example, in some cases, perhaps email is not a commodity. Perhaps there are some Outlook customizations for sales force automation, ACT plugins or whatever, that makes email a tool instead of a commodity. But, even then, it illustrates the point… using, and email, you want to bring that information together. The more you can do that… the more relevant IT will be. Yet, when each app is a closed silo, where the efforts are on integration rather than connectivity, it becomes a real challenge to leverage the cross-app data and relationships.
  • Not talking about ESB- or inter-app style messaging. I’m talking about email messaging. There are messages that are part of the conversation everywhere. But they lose context in email. Yeah, maybe there is a link back to relevant information, but it’s very very basic integration that doesn’t even server technical users well. We want to bring information together. Best example I can think of, however trivial, are those silly facebook messages that say “you have an email” but, I can’t respond, I need to go to facebook and respond. I have messages all over the place, there is no reason why Facebook, LinkedIn, Twitter, Email, Progress, and all these places have different places where I have to go and bring this information together manually.Now, this (messaging) is maybe not important to my enterprise, but other similar things are. How about, customer information. There is customer information all over the place, in the sales force automation system, in the provisioning system, in shipping, maybe in contracts administration, etc. Maybe in multiple places. It’s not just about Master Data Management, and having a uniform customer record (that’s hard too), but it is about having a view on my relationship with the customer so I can make better business decisions.
  • If all IT does is integrate (data and processes), it will have to become more disciplined, and there will be time to do so. I believe clouds help us get rid of the low level things IT focus on, to help us raise the bar and focus on what’s important.New classes of applications: Really more mashup-like, rapidly created, possibly with short lifespans, that help users synthesize and visualize relevant data and events so they can better execute the business. Data is no longer locked into the silo. In fact, silos simply disappear and we have a full federation of services.
  • This is really less of a definition, and more of putting an edge around a concept. And, that edge doesn’t fully surround the concept, only it gives it some shape.
  • Visibility, protect from change, service level management.
  • When I was working at Radianz, I was responsible for delivering a middleware layer on top of a shared network. Forget the technology. One of the big problems was around culture and contracts. If the network was up, but the middleware service was down, it was down from the customer perspective, and they’d want a refund. However, the network people were bonused on network uptime, not on middleware uptime, so they didn’t look at it the same way. Then, our customer support needed to be trained not to say “well, the network is up” to the customer, why would the customer care? It wasn’t working from their perspective. This is a hard problem, least so with respect to technology.
  • Security needs to change to application or message layer security. Today we rely too heavily upon network layer efforts, and frankly, it’s just not secure enough. We know that, but it’s hard to change. I believe this resistance to change will hinder cloud efforts.

    75. 75. Understanding Cloud Computing<br />
    76. 76. Origin<br />“.. Comes from the early days of the Internet where we drew the network as a cloud… we didn’t care where the messages went… the cloud hid it from us” – Kevin Marks, Google<br />First cloud around networking (TCP/IP abstraction)<br />Second cloud around documents (WWW data abstraction)<br />The emerging cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms<br />(“muck” as Amazon’s CEO Jeff Bezos calls it)<br />
    77. 77. 3 Cloud Service Models<br />Cloud Software as a Service (SaaS)<br />Use provider’s applications over a network <br />Cloud Platform as a Service (PaaS)<br />Deploy customer-created applications to a cloud <br />Cloud Infrastructure as a Service (IaaS)<br />Rent processing, storage, network capacity, and other fundamental computing resources<br />To be considered “cloud” they must be deployed on top of cloud infrastructure that has the key characteristics<br />
    78. 78. Service Model Architectures<br />
    79. 79. 4 Cloud Deployment Models<br />Private cloud <br />enterprise owned or leased<br />Community cloud<br />shared infrastructure for specific community<br />Public cloud<br />Sold to the public, mega-scale infrastructure<br />Hybrid cloud<br />composition of two or more clouds<br />
    80. 80. Common Cloud Characteristics<br />Cloud computing often leverages:<br />Massive scale<br />Virtualization<br />Non-stop computing<br />Free software<br />Geographic distribution<br />Service oriented software <br />Autonomic computing<br />Advanced security technologies<br />
    81. 81. is this GRID Computing?<br />
    82. 82.
    83. 83. Clouds aren’t all the same<br /><ul><li>Not every cloud is a “grid”
    84. 84. Grids imply dynamic arrival/departure
    85. 85. Electrical analogy has limits: CPU cycles aren’t substitutable
    86. 86. Most clouds are not “compute clusters”
    87. 87. Clusters are typically monocultures: just one type of node
    88. 88. Applications may require tuning to a particular cluster size
    89. 89. Some clouds are servers in virtual slices
    90. 90. Virtualized servers can be quickly provisioned
    91. 91. Spin-up of instances = new management task
    92. 92. Hardware gets cheaper, management…not so much
    93. 93. Enterprise cloud computing implies API leverage
    94. 94. Immediate focus on function; immediate delivery of value
    95. 95. Using appropriate frameworks enables a huge head start</li></li></ul><li>Single-Tenant (vs) Multi-Tenant Architecture<br />Shared infrastructure<br />Other apps<br />App 1<br />App 2<br />App 3<br />App Server<br />App Server<br />App Server<br />Database<br />Database<br />Database<br />OS<br />OS<br />OS<br />Server<br />Server<br />Server<br />Storage<br />Storage<br />Storage<br />Network<br />Network<br />Network<br />Single tenancy gives each customer a dedicated software stack – and each layer in each stack still requires configuration, monitoring, upgrades, security updates, patches, tuning and disaster recovery.<br />On a multi-tenant platform, all applications run in a single logical environment: faster, more secure, more available, automatically upgraded and maintained.
