Cloud Hosting vs Apps Hosting
Bernard Golden explains why some companies think cloud computing is the same as Hosting 2.0. They are running into problems putting apps on platforms like Amazon. Stating “cloud scalability isn’t the same as application scalability, and unless you architect a cloud app, you aren’t going to garner the benefits of cloud computing. In our workshops, we phrase this as “build cloud apps, not apps in the cloud.”
Here are 4 of his reasons:
1. Applications are installed on Amazon Machine Images and run just fine, but if the EC2 instance crashes or needs to be terminated, the app is out of commission until a new instance comes on line.
2. If an EC2 instances gets overloaded, there’s no way to add more resources to improve app performance.
3. No way exists to update the application without taking it completely offline.
4. Performance gets bottle necked by the database, but there’s no manageable way to move to database replication.
Application hosting is going to be huge in the future and having a system that can support iPad and iPhone applications without the bottleneck will be very valuable. Scalable iPad Hosting and scalable iPhone Hosting application is the wave of the future. You can read all about Bernard Golden and everything he talked about apps hosting and cloud hosting.
