Links about High Availability and NoSQL
I’m reading many links about High Availability, Elastic Systems and NoSQL alternatives. It’s all about alternatives for scaling a system where a RDBMS can’t fill it needs.
We are putting them below, with some messages and images. It’s a pleasure to read for anyone that works with Distributed Systems:
NOSQL Patterns – How we can build a distributed database
This article describes the principal NoSQL alternatives and how to split a table/dataset by key an put them into many servers, how map reduce occurs in the cluster nodes, all with beautiful diagrams.
RoadMap to SaaS
How to convert a standard web application in to a SaaS with Facade class with RESTFul services, moving processes for diferents JVM’s, cache tiers and much more…
Observers: Making ZooKeeper Scale Even Further
Maybe you won’t know about Zookeeper, yet. But you can be interested in what you can do to scale servers who depend on distributed communication and synchronization. That is a big trouble: How much more computers you put in the cluster, more messages to coordinate the distributed lock between them. The throughput decreases. But not for this guy’s using followers and observers!
Boa Noite,
Gostaria de perguntar se você poderia fazer uma matéria ou me informar um site para que eu possa estudar um pouco mais sobre o TestComplete, uma dessas minhas dúvidas é como identificar um DBGrid dentro de um Form usando essa ferramenta.
Obrigado,
