Task – B  

1. Cloud service provider

There are so many cloud service providers present in the market today who are providing cloud services to host our servers and a lot of services on the cloud. Also, there is a huge competition in this service field. From a big list, the two best suitable cloud service providers are described here –

• Amazon Web Services – Amazon aws provide a secure and managed platform to host our servers. There are many options available to deploy the web and email server on cloud. Either we can use prebuilt services or we can deploy our own virtual machine to run the required services. Amazon Work Mail is a service to be used for business email (Amazon Web Services, Inc. 2019). That support all the desktop and mobile email clients. It provides enterprise level security like encryption by using aws-kms and compatible with MS outlook on both windows and Linux Oss. It also supports mobile device access, active directory integration with a monthly cost of around $4 per user / month. Amazon Web Hosting service provide a huge platform to configure a web server (Amazon Web Services, Inc. 2019). It has broad platform to support CMS like WordPress, java, node.js joomla etc. Data that works with this web server are stored on a large worldwide data centers that can be scale up/down any time with the good competitive pricing. 
• Microsoft Azure – Microsoft also has a large service platform to deploy so many services either on separate virtual machine or individual service. Microsoft SendGrid email is a service that is provided to configure the email service (Docs.microsoft.com. 2019). It is a cloud based email service that provide real time email delivery and compatible with APIs. Microsoft recently announced Azure Web Sites service to host web servers on the Microsoft cloud (Azure.microsoft.com. 2019). It is very simple to configure this web service on azure with several benefits like auto scaling, standard instance, access control and with better isolation. 

2. Cloud computing with dynamic scaling 

When we are moving to cloud computing, it gives a lot of benefits in many fields like, computing, infrastructure, database, services etc. The best benefit of using a cloud is its scalability features (IronOrbit. 2019). Today, every cloud service provider has on demand scalability feature. It allows a user to scale up or down our cloud resources any time. For example increasing hardware resources, storage, memory, virtual machines or other services. Scalability in a cloud can be defined as growing our deployed infrastructures on cloud. This scalability works in three ways (Rick's Cloud. 2019) –  

1.  Vertical scaling - this will scale our server or other infra to "up". that means we are increasing our resources on cloud like memory, computing resources, storage or servers etc. Whatever we need, we just add to our infrastructure according to our need and pay for what we use.
2. Horizontal scaling - this scaling is used to decease our cloud resources or minimizing them to a single system. horizontal scaling contains deploying new servers and configure then to work together. it will take more time to build a new server rather than increasing the previous built server. but it is beneficial in case when we need different services to run on different servers to decrease response time.
3. Diagonal scaling - it is a combination of vertical and horizontal scaling. it can scale us cloud infrastructure to increase cloud resources as well as can increase servers to add more services or resources.
