Architectures for the cloud
This presentation looks at the hardware and software issues for building the infrastructure of "the cloud": network infrastructure evolution, hardware trends in the servers, virtualization and private VLANs, storage, and the implications for applications. It argues that we have to start treating a large datacentre installation as a single machine, and an application brought up in such a datacentre as a single application. It will show how Hadoop and layers on top of Hadoop form the ideal platform for much of the system, how other Apache products fit in to other parts of the datacentre, and where there are gaps in the portfolio. Everything from Log4J to Tomcat needs to adapt to this world —this talk looks at the issues and the opportunities.
