Cloud
computing is mainly storing and accessing data in the Internet
instead of the hard disk of your computer. With an online connection,
cloud computing can be done anywhere. Google Cloud Dataflow, the
successor to the much acclaimed MapReduce service, is a managed
service that enables the android
developers
to create data pipelines that analyze data in both batch and
streaming modes. MapReduce was processing the massive data sets using
distributed computing. But now MapReduce stands outdated.
Google
has introduced cloud dataflow which will give you actionable insights
from your data. There are no problems regarding deploying,
maintaining or scaling infrastructure. Google cloud monitoring system
will assist you to discover and fix strange behaviour of your
application stacks. Constant error showing in app engine module and
sluggish query times from cassandra database with minimal
configuration, will be solved by Cloud Monitoring.
Google
Cloud Messaging (GCM) was a replacement for Cloud to Device Messaging
(C2DM). With GCM, app
developers
can develop their mobile apps on devices and web browsers and can get
easy communication whatever be the location or kind of network. With
this android platform API, sending and receiving push notifications
are possible. Thus GCM is a boon to every android
app developer.
Server application for google cloud messaging can be written in both
Java and PHP. GCM is a lone file application in PHP. You can put it
in Apache.
GCM
android app prerequisites are google play services in SDK, Google
APIs, Google Play Services Lib project as Android dependency, Google
Project ID and Register/login with a Google account in the AVD.
App
developers can use google cloud messaging as a
notification engine. Unlike a send-to-sync message, notification of
up to 4 kb of payload can be sent to an android app. The app will get
this message from google cloud messaging server. Now with the new
feature Return receipts, you can be sure that a message is sent to a
device. For this upstream messaging is to be used.
Android
developers can also make use of the GCM feature,
canonical registration IDs, to recover from bug-generated multiple
registrations for the same device.
