The main commercial cloud providers are1:Amazon web services (AWS) EC2, Microsoft Azure , IBM's Spectrum Computing, Google Cloud Platform and Fujitsu Cloud Service K5. However, planning cannot always cover sudden spikes in traffic, and manual provisioning might be required. There are also cloud platforms and "computing as a service" providers that are focused on HPC and performance. Cloud Computing is a technology in which different users are able to access computing facilities from a single multi-provider who normally has the requisite infrastructure and or software and vends them out for a fee. Hybrid Cloud. A The cloud has many advantages and it OVERVIEW CLOUD COMPUTING : means storing and accessing data and programs over internet instead of your computer’s hard drive. Companies can keep cloud computing costs low by implementing these … Let's look at five tips on how to better troubleshoot application performance in public cloud or hybrid cloud environments.
