- Explain "EUCALYPTUS" in cloud computing.
"Eucalyptus" is an open-source software infrastructure, which is utilized to actualize clusters in cloud computing platforms. It is utilized to construct public, hybrid and private clouds. It can create your own data community into a private cloud and permits you to utilize its usefulness to numerous different organizations.
- Why is cloud computing important for business?
Cloud computing has settled numerous modern challenges for organizations and people that we experience in standard life. It might range from getting and maintaining reasonable hardware and software to smooth out the resources most proficiently. The four most fundamental advantages cloud computing is providing are: efficiency, flexibility, scalability and strategic edge.
- Mention some open source cloud computing platform databases
The open-source cloud computing platform databases are
CouchDB
MongoDB
LucidDB
- Name the layers of cloud computing.
The layers of cloud computing are as per the following:
- CLC or Cloud Controller
- Cluster Controller
- Walrus
- Node Controller (NC)
- Storage Controller (SC)
- What is on-demand functionality in the cloud?
With cloud computing, you can get on-demand access for virtualized IT resources. It utilizes a shared pool to provide configurable resources. This shared pool contains systems, applications, storage, servers and services.

- What is Memcached?
Memcached is an open-source distributed memory caching system. It is a free system that assists with improving the data response time by accelerating dynamic web applications.
- Tell us the benefits of using Memcache.
Memcache serves to:
- Accelerates the application processes
- Sets up which components to store
- Lessens page load time
- Chops down the input/output access
- What is a VPN?
Virtual Private Network (VPN) is a network connection technique for making an encoded and safe connection. This strategy shields data from censorship, snooping and interference. VPNs are used for adding security and protection to private and public systems, such as Wi-Fi hotspots and the internet.
- What are the various cloud deployment models?
These are the different cloud deployment models:
- Public cloud
- Private cloud
- Community cloud
- Hybrid cloud
- What is a private cloud?
Private clouds keep the key tasks and different operations secure. This platform is completely functional. Private clouds can be owned, worked and confined to just a single organization or an industry. Presently, a large portion of the organizations has migrated to private clouds because of security reasons.
- What is a public cloud?
The public cloud is available to the individuals for use as well as deployment, such as Google, Amazon, Azure and so on. The public clouds center around a couple of layers like infrastructure providing and cloud application.
- What is a Hybrid cloud?
Hybrid cloud is a hybrid of private clouds and public clouds. This cloud model is favored over both the clouds, since it has the most vigorous way to deal with cloud architecture. It incorporates the features and functionalities of each cloud model. It permits organizations to make their own cloud and also allows them to give control over to another person.
