Cloud computing is gaining tremendous momentum. This has given EdTech’s a heads-up on the fact that the segment has witnessed a quantum leap and there is a gap in the workforce for cloud practitioners that need to be filled with immediate effect. Prominent cloud computing platforms like AWS and CompTIA have collaborated with EdTech companies in lieu of creating co-certified courses, giving learners and professionals a chance to place themselves more amiably in a segment that is rife with opportunities.
To ensure you successfully carve a niche as a cloud practitioner we have come up with a cheat sheet of some compelling interview questions that can help you make a breakthrough in the segment.
1) What is Auto-Scaling in Cloud Computing?
There is a lot of debate around auto-scaling in the world of cloud computing.
Auto-Scaling is an option provided by cloud providers to allocate extra resources from the cloud when there is an operational load. Auto-Scaling needs to be used wisely, and rigorous load testing needs to be done before the system is operational.
2) What can a user gain from utility computing?
Utility computing takes a slight departure from cloud computing. Its entirety is based on computing services. Customers will get computing resources through a service provider and they are entitled to pay only as much as they consume. The only advantage of utility computing is that it is commercially viable.
3) Security aspects provided with the cloud?
Security is one of the major aspects that come into play with any application or service used by a user. Companies remain more concerned with the security provided by the cloud. Below are some of the security aspects a cloud provides:
- Identity management: it authorizes the application service or the hardware component to be used only by authorized users.
- Access control: permission provided to the user so that they can control the access of other users who are using the cloud environment.
- Authorization and authentication: provisions have been made to enable authorized and authenticated persons to access and change the applications and data.
4) Difference between Cloud Computing and Computing for Mobiles?
Cloud computing can help us in storing and organizing data and information, whereas mobile computing provides access to this data and information through a mobile device.
5) What is the difference between Scalability and Elasticity?
Scalability is used to manage any static increase in workload. To manage any increased traffic and accommodate larger loads, we add in resources.
Elasticity is used to meet the changes where the resources can either be increased or decreased. In Cloud Environments, elasticity is the most important where you want to pay-per-use and do not want to pay for resources you don’t currently need.
EUCALYPTUS stands for Elastic Utility Computing Architecture.
It is an open-source software used to implement clusters in a cloud computing platform. It allows a user to make his own data and then use its function for other organizations.
7) What platforms are used for large-scale cloud computing?
The main two platforms used for large scale computing are
- Apache Hadoop and
8) What is the role of API in cloud computing
API or Application Programming Interface eliminates the workload to write full-fledged programs. For instance, If my website wants to use login information from Facebook, I will have to use the Facebook API. This directs me to my login details from the Facebook database rather than creating a new database.
9) For Transport in the Cloud how can you secure data?
When transporting data in cloud computing, two things are certain to be kept in mind: Making sure that no one can intercept your data while it moves from point A to point B and ensuring no data leaks. The security process includes segregating data from other companies’ data and then encrypting it with an approved method. A virtual private network (VPN) is one of the ways to manage the security of data during its transport in a cloud environment.
So there may be the most basic questions to advance or even tricky cloud computing questions you might encounter, but if you have done the homework, that job is yours!
