●Avoid rollback with incompatible db migrations

Sentinel

● Much faster

● Asynchronous

● Assets are pre-fetched

● Manages downtime better


Buildpacks

● Specify by URL

● Always up-to-date

● Freedom for developers

● Fork 'n' change

● Open-source

● Configured by developers


Admin Buildpacks

● Installed by Stackato administrator

● Upload (from git, zipfile, local filesystem, url)

● Transparent to developers - it just works!

● Admin can change order of detection

● Does not restrict developer choice

● Can be "online" or "offline"...

3.4

Previous Stackato Micro Cloud License

● Restricted to 4GB RAM

● Single instance

● No clustering

● No redundancy


New Stackato Cluster License

● 20GB RAM

● Clustering (any number of nodes)

● Free

● Community Support

● Suitable for Production

● Bring your own Infrastructure


Sample Micro Cluster Setup

20GB can be broken down nicely into a five

node Stackato cluster of 4GB instances:

●1 Core Node

●1 Data Node

●3 DEAs



1 Core node running the base, primary,

controller, and router roles. This is the node that

exposes the API, a web interface, and a

gateway to the applications from the outside

world.



1 data service node running whichever built-in data

services you would like to expose to users (e.g.

Redis, Filesystem, MySQL, PosgreSQL, etc.).

3 "DEA" nodes where the application containers

run.


Other 3.4 Features

● Additional Dashboards

● Easier Administration

● Logging Improvements

● Cloud Foundry and Docker Upstream Merge

● Docker upgrade to 1.0
