Next Generation Enterprise Application Architecture

New generation applications are architectured not only with the goal of desiging the application functionally and performing stable but also focuses on different aspects that are becoming critical

Scalability – Elastic scalability for all the layers of the application including data tier

Fault Tolerance - Ability to handle failure smartly and avoid cascading failures from and to dependent systems

High Availability – Ability to have application highly available on all layers including database even on data center failures

Efficient utilization of Infrastructure - Ability to scale up and down on demand

Faster access to underlying data on high load and data volumes

Ability to handle different data formats efficiently

Few reasons that are tied to this evolution are the need and benefits towards cloud adoption ( could be either private or public cloud ) and the need to handle huge data volume with faster response on the data tiers

	Benefits	Solutions
Physical -> IaaS -> PaaS	Elastic Scalability High Availability Efficient Infrastructure utilization Zero downtime deployment	VMWare , Open Stack – Private Cloud IaaS AWS, Azure – Public Cloud IaaS , PaaS Cloud Foundry – PaaS on private and public cloud
Circuit Breaker	Fault Tolerance Better failure handling Avoid avalanche failures	Netflix Hystrix Polly
Service Registry	Registry for dynamic instance scaling	Netflix Eureka Apache Zookeeper
Intelligent Load balancing	Intelligent Load Balancing utilizing the elastic scaling and self-discovery	Netflix Ribbon F5 Nginix
Search	Quick search needs from huge data sets, full text search, pattern matching	Elastic Search Solr
Data Grid	Faster read write data, Reduce read / write overhead to database, high availability to data	Coherance Gemfire Membase
Queue	Reliable data transfer across different data layers	Kafka RabbitMQ JMS
NoSQL	Big data – database needs Heavy Read / Write on high data volumes Faster response needs on the data High Availability on data Fault Tolerance on data Distributed database Scalable database	Couchbase MongoDB HBase Cassandra Graph DB ( Titan, OrientDB )
Hadoop	Distributed file processing and storage ecosystem High speed batch (MapReduce) / real time ( Storm, Spark ) processing	Different Hadoop distributions like Hortonworks, CloudEra,MapR
