Explanation: A service-level agreement (SLA) is defined as an official commitment that prevails between a service provider and a client . Particular aspects of the
service quality, availability, responsibilities are agreed between the service provider and the service user. The most common component of SLA is that the services should
be provided to the customer as agreed upon in the contract. As an example, Internet service providers and telcos will commonly include service level agreements within the terms of
their contracts with customers to define the level(s) of service being sold in plain language terms. In this case the SLA will typically have a technical definition in
- mean time between failures (MTBF)
- mean time to repair or mean time to recovery (MTTR)
- identifying which party is responsible for reporting faults or paying fees
- responsibility for various data rates; throughput; jitter; or similar measurable details.

Correct Answer : Get Lastest Questions and Answer :
Explanation: Component based software engineering (CBSE) is a known and tested approach in software engineering. The approach was inherited from the object based
approach. In addition, it incorporates the concept of middleware, software architectures and Architecture Definition Languages (ADLs).

The component model consists of the components, configurations, folders, and files to which you can map various design constructs of the software model.
Components
Components are binary-level entities that are the result of compilation. Libraries (.lib files) and executable programs (.exe files) are the final output of the build process with
the source files generated by IBM Rational Rhapsody.

4. Spark and YARN

5. Slider and YARN

Correct Answer : Get Lastest Questions and Answer :
Explanation: Apache Slider is a YARN application to deploy existing distributed applications on YARN, monitor them, and make them larger or smaller as desired, even
while they are running.

Slider is a framework for deployment and management of these long-running data access applications in Hadoop.

Slider leverages YARN resource management capabilities to deploy those applications, to manage their lifecycles and scale them up or downeven while the application is running.
Slider slides existing long-running services (like Apache HBase, Apache Accumulo and Apache Storm) onto YARN, so that they have enough resources to handle changing amounts of
data, without tying up more processing resources than they need.

Apache Slider allows users to create and run different versions of heterogeneous long-running applications in Hadoop with YARN. Each application instance can be configured
differently, with its operational life cycle managed individually. On an on-demand basis, Slider can expand or shrink application instances while they are running. In the case of
container failure, Slider transparently leverages YARN facilities to manage application recovery. All of this is available on Linux or Windows platforms.
