How to Design an Effective Virtual Machine on Cloud
Cloud is one of the booming industry which has automated the way of operating procedures for companies as well as individuals. All you need is a proper internet connection and few clicks. It has reduced the complexity involved with traditional business operations and IT management.
Designing a machine architecture on the cloud is not an easy task. Cloud architects are responsible for this effective work. It is their responsibility to create a completely secure, reliable and cost-efficient machine with best performance results. The fully automated elastic feature reduces the effort and cost for designing and managing infrastructure, storage, application-based services. To achieve full hand on experience in designing and configuring product in the cloud, you must obtain a cloud certification taught by industries experts with well-maintained syllabus structure.
Some principles must be acknowledged before designing an effective machine for your organisation are listed below:
Availability Zone & Machine Image:
Availability zone is a region which provides access to virtually acquire resources. Basically, the services provided to you by your provider are physically installed in their data center’s. These availability zones refer to those data centers’ where all these devices are securely established and are made available to you.
You are required to design an effective machine for creating or deploying your server on cloud. The first step will ask you to select machine image for your product. It is a template framework over which your operating system gets installed. It can be chosen according to your system architecture requirement from 32/64-bit type. It is a framework for root volume needed in particular kind of instance.
Operating System Installation:
Now you have selected the appropriate machine image for your organisation; you are ready to install the operating system for the selected image. There is a vast marketplace available on the internet for cloud where you can choose the OS of your need. It can be Ubuntu, windows, sun microsystem, etc., you can select anyone of your choice from the variety for your business requirement.
CPUs and RAM:
One of the very outstanding features of the cloud is that you can add or remove any number of resources remotely anytime. All you need is a compatible device for accessing your acquired resources. E.g., tablet, laptop, PC etc.
Now you have an installed operating system on your cloud machine. You have to add processing units and random access memory for making it configure to support your requirements completely. Select the number of CPUs you want to add to your machine depending upon the load it can handle. If your problem scenario can be controlled by single thread processing or it need multithreading, you can add CPU in batch or parallel processing with the desired number of RAM.
In the cloud, you can add or remove sufficient storage for your machine. It can be either 1GB or 100 of TBs; it is available under your fingertip. The storage service offers varieties of memory devices depending upon the maximum input-output processing speed, throughput requirement. You can select disk storage types from solid state drive, hard disk drive or IOPS SSD carefully on their life and throughput basis.
World wide web is not a secure place it is open to the world on port 80 of hypertext transfer protocol. You cannot leave your machine open to the world by merely opening HTTP port. You can configure the security of your device by adding security layers in them. You can open machine connection at limited ports and add networking protocols for establishing a secure connection like HTTPS, SSL, sFTP, etc., during its usage. Implementing access management for providing limited identity credentials for accessing a part of the machine. You can define specific IP to connect to the machine with various protocols to perform add/remove file operations on it. If you feel little insecure about your data then select virtual private cloud and configure it as you want.
To add or remove resources the auto scaling feature of the cloud is the best available feature in the market. You just take care of your business operations rather than spending time on maintaining your server. The auto-scaling service will add resources demanded by your machine in case of substantial onsite traffic and remove when traffic is low and extra resources are not needed to balance machine load.
Adding load balancer is also a good habit for managing traffic on your server. It will equally distribute your traffic between machine.
