Editor's Notes
- Funny Start Sogeti Commercial Part of the Capgemini Group 130,000 Sogeti has 20K, USA Head Quarters in Dayton, USA has 2,000 Cap focuses more on business strategy, we are technology focused. They travel 100% of their time, we are local providers We go across the entire SDLC from Analysis, Design, Development, Testing and Infra using a wide variety of tools and technologies.
- Apple changed the game for Software Engineers. Clients want everything fast with frequent updates. Think Minimally Viable Product. The applications must run everywhere. This was Java’s promise. Solutions are open & integrated to each other. Salesforce. Features are distributed by platform but must be designed for extended use (explain the table). No one wants heavy, monolithic applications, We want solutions to be lightweight and free. Oh and they better be attractive or I’m not interested.
- Author of Consumption Economics is JB Wood, Todd Hewlin, Thomas Lah, Technology Services Industry Association Capital expenditures are hard to secure, take time to implement. We have buy them long before we use them. SaaS is a just-in-time model. Buy only what you need, when you need it. Highlight the ability to drop test/dev and save money when not being used. Note that total spend will cross if use of all environments is heavy for a long durations.
- Maybe talk about years Key message is that we’re less strict now Describe the difference between SARA source code and Sogeti guidelines
- Strengths and weakness of the tools in a visual manner? Maybe talk about the languages supported?
- Producer/consumer model. We’ve been here before. Why now? Make it funny.
- BlueMix status site
- Azure Status Page
- OneShare. Unique Sogeti application to shutdown applications when they are idle between specific time periods.
- Start with big picture then go into the data
- Lots of data here, pick a couple to highlight.
- Talk through the process and highlight why this is an issue.
- Pick two or three key components; discuss the issues and the benefits Mention that Microsoft hasn’t already addressed these.
- Talk about all phases but go deep on only a few. Address the benefits at each step.
