• Log data can be stored and accessed indefinitely in highly durable, low-cost storage. • The data can be accessed directly, as text and numerical output that can then be analyzed or manipulated, or viewed in more mediated formats, such as graphs. • We can have CloudWatch keep an eye on the processor load of an EC2 instance. The metric can be configured to generate an e-mail alert if the processor load percentage rises above a certain level or even trigger a programmatic action such as an Auto Scaling
Special programming techniques are required to exploit HPC capabilities. The most Common programming paradigm in such machines is message passing. Each node is allocated a small part of the overall problem and they communicate through coordinated message passing. Message Passing Interface (MPI) implementations provide scalability and portability without
If we use pure hash in the password and encrypt it, it can be broken easily by exhaustive search so that is why we have add some randomness to the password before the hash function is applied. The randomness is stored with the password hash. So now instead of pure hash and pure password we store the hash o/p of password chosen by me and some random number chosen by the system. From now whenever we use the password the system associates with the random number and gives access. This is how a hash is used in password storage.
Not only will these innovations improve network strength, but possibly the speeds at which a client can access information from an application server. This has the potential to make cloud computing even more prevalent than it already is today because it would become easier to keep up with mass traffic to the servers. Large server banks would be able to be downsized slightly compared to their current sizes. The computer science techniques used in created Marple show that it is possible to even make an old process useful in modern applications. The hardware of Marple is also programmable making it extremely useful for any network engineers because they will be able to write custom software for Marple-based
4. OpenVPN—Open VPN is open source and it uses other ope-source technologies like SSL v3/TLSv1 and OpenSSL encryption library protocols. It is not port specific and can be configured on any port. This feature enables OpenSSL VPN traffic indistinguishable from other HTTPS traffic and not easily gets blocked. AES encryption makes it more secure than blowfish encryption.
However, due to this reason, it occupies more space compared to Vector graphic and take longer time to transfer over network. Furthermore, Vector graphic is resolution-independent, it means that quality of Vector graphic would not be affected by zooming like Bitmap graphic does. There are a few standard formats for Bitmap graphic on the Web, such as GIF, JPEG/JPG, PNG, TIFF and
1. Bitcoin is known as a cryptocurrency because it uses cryptography. Cryptography basically makes any transaction secure between two parties. Security is very important, because every person with Bitcoins, their Bitcoins, and every transaction is logged to a public ledger visible by every computer on the
1. Discuss the differences and similarities between a peer-to peer network and a client server network. Answer: The following are characteristics of a peer-to-peer network that differ from those of a client server network. In a peer-to-peer network the operating system of each node or host is responsible for controlling access to its resources without any centralized control. This type of network has decentralized management of its administration, system performance, resources and security.
In this system of storage, in support of Deduplication method, a user uploads only unique single data copies/files although it is impossible for them to upload any duplicated data files. In this system, each of user who has concerned with set of level of privileges i.e. privilege levels (e.g. upload, download) is the settled down in the system. Each file is said to be safer or protected by having both the keys named CE key and PE key.
Explain the growth trend in this area With any network, you need to provide several resources for your users, but chief among them is security. Security starts with ensuring that only the right people have access to your network, and that they only have access to what they are supposed to have access to. Next comes the ability to ensure that communications are protected, and systems are inspected for vulnerabilities and threats. Identity as a Service (IDaaS) is a solution that provides authentication infrastructure as a cloud service. IDaaS is a service that provides Identity and Access Management (IAM) functions for a company in place of a local solution like Active Directory.
Active Directory is a lot more user friendly than OpenLDAP as well as a lot more “feature-rich”. Linux is definitely more host-centric where everything is determined by the machine itself that is being used. I like the fact that Active Directory takes a different approach and makes it easy to manage your network based on the machine, but easily apply other rules as well. Active directory allows for groups to easily migrate from machine to machine if the need is there. Since much of the security is based on the user or the group that the user is in, this free-floating ability
