How long did it take to get your application running online 10 years ago?
When it was time to deploy your software...
...2 sizes fits all!
Pre-cloud Era
Shared Hosting
Pre-cloud Era
On Premise
Pre-Internet Era
- There was never so much need for computer power:
- local desktop
- local networks
- Programming languages and tools were enough for the tasks.
- The same happened with databases.
- Redundancy was something for just a few.
Post-Internet Era
- Your applications can reach millions (and even billions) of users;
- For worse (or better): it can happen in a short time
- You need to be ready to go from dozens => hundreds => thousands => millions.
But at this time...
So it comes the cloud!!!
- Allows the increase of computing power in a gradually
- The amount of resources increase when the demand for them increase too:
- more traffic = more resources
- cost increases only when $$$$ increases
- fine tuning of each component
- less downtime
- no resources waste
Post-Cloud Host
