#Top sub-modules in Cloud Computing Technology Architecture:
The main architectural characteristics of a cloud computing environment. One fundamental architectural aspect of a cloud is heterogeneity. A cloud must support the aggregation of heterogeneous hardware and software resources, as it happens with scientific experiments. The concept of virtualization is also a key aspect for clouds.

Through virtualization, many users may benefit from the same infrastructure using independent instances. Virtualization enables the first security level in the clouds, since it allows the isolation of environments. In clouds, each user has unique access to its individual virtualized environment.

Cloud Architecture
  1. Virtualization
  2. Heterogeneity
  3. Security
  4. Resource sharing
  5. Scalability
  6. Monitoring
Resource sharing is provided by clouds, since each resource is represented as a single artifact, giving the impression of a single dedicated resource. Scalability is mainly defined by increasing the number of working nodes. By definition, clouds offer the automatic resizing of virtualized hardware resources. Monitoring refers to the ability of watching the current status of virtual machines or services provided.

Each one of those architectural characteristics is standardized by specific standards (which are in another class of the taxonomy). Besides that, some architectural characteristics are important to scientific experiments, such as scalability and monitoring to control the execution.

Top Differences Read Today Agile vs Waterfall model

The Agile and Waterfall both models are popular in Software development. The Agile model is so flexible compared to waterfall model. Top differences on Waterfall vs Agile give you clear understanding on both the processes. Waterfall ModelThe traditional model is waterfall. It has less flexibility.Expensive and time consuming model.Less scalable to meet the demand of customer requirements.The approach is top down. Starting from requirements one has to finish all the stages, till deployment to complete one cycle.A small change in requirement, one has to follow all the stages till deployment.Waterfall model creates idleness in resource management. Agile ModelAgile model is excellent for rapid deployment of small changesThe small split-requirements you can call them as sprintsLess idleness in resource management.Scope for complete team involvement.Faster delivery makes client happy.You can deploy changes related to compliance or regulatory quickly.Collaboration improves among the team.
