What is EFS storage in aws? and Benifits of EFS


Amazon Elastic File System (Amazon EFS)


Amazon EFS is a regional service storing data within and across multiple Availability Zones (AZs) for high availability and durability. Amazon EC2 instances can access your file system across AZs, regions, and VPCs, while on-premises servers can access using AWS Direct Connect or AWS VPN.
What is EFS storage in aws? and Benifits of EFS


EFS is the best choice for running any application that has a high workload, requires scalable storage, and must produce output quickly. It scales automatically, even to meet the most abrupt workload spikes. After the period of high-volume storage demand has passed, EFS will automatically scale back down. EFS can be mounted to different AWS services and accessed from all your virtual machines. Use it for running shared volumes, or for big data analysis. You’ll always pay for the storage you actually use, rather than provisioning storage in advance that’s ultimately wasted.

Benefits of EFS:


  • Performance that scales to support any workload: EFS offers the throughput changing workloads need. It can provide higher throughput in spurts that match sudden file system growth, even for workloads up to 500,000 IOPS or 10 GB per second.

  • Energetic elasticity: Automatically scale your file system storage up or down. Remove or add files and never disturb applications. Once you make your EFS file system you can add files without worrying about storage provisioning.

  • Accessible file storage: On-premises servers and EC2 instances can access shared file systems concurrently. EC2 instances can also access EFS file systems located in other AWS regions through VPC peering.

  • Comprehensive managed service: EFS is a complete managed service, meaning your firm will never have to patch, deploy, or maintain your file system.

  • Cost savings: The only storage you’ll pay for is exactly what you use, as there’s no advance provisioning, up-front fees, or commitments. Moreover, you can use Lifecycle Management to transfer files that have been unused for a month to a more cost-effective storage class, which can lower expenses up to 85%.

  • Tighter security and compliance: You can securely access the file system with your current security solution, or control access to EFS file systems using AWS Identity and Access Management (IAM), Amazon Virtual Private Cloud (Amazon VPC), or POSIX permissions. And, EFS can encrypt your data, whether it’s in transit or at rest. This gives you dependable security and makes regulatory compliance easier.

Use Cases of EFS


  • Lift-and-shift application support: EFS is elastic, available, and scalable, and enables you to move enterprise applications easily and quickly without needing to re-architect them.

  • Analytics for big data: It has the ability to run big data applications, which demand significant node throughput, low-latency file access, and read-after-write operations.

  • Content management system and web server support: EFS is a robust throughput file system capable of enabling content management systems and web serving applications, such as archives, websites, or blogs.

  • Application development and testing: Only EFS provides a shared file system needed to share code and files, across multiple compute resources to facilitate auto-scaling workloads.

What is STP? - Explain Advantages and Disadvantages

The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. STP is a protocol. It actively monitors all links of the network. To finds a redundant link, it uses an algorithm, known as the STA (spanning-tree algorithm). The STA algorithm first creates a topology database then it finds and disables the redundant links. Once redundant links are disabled, only the STP-chosen links remain active. If a new link is added or an existing link is removed, the STP re-runs the STA algorithm and re-adjusts all links to reflect the change. STP (Spanning Tree Protocol) automatically removes layer 2 switching loops by shutting down the redundant links. A redundant link is an additional link between two switches. A redundant link is usually created for backup purposes. Just like every coin has two sides, a redundant link, along with

What are the Advantages and Disadvantages of TCP/UDP ?? Difference between TCP and UDP

As in previous blog we have define and explain about what is TCP and UDP and from now we are moving ahead with Advantages, Disadvantages and Difference of TCP and UDP but for this you have to know about TCP and UDP hence to understand it go for a What is TCP and UDP . Advantage of TCP Here, are pros/benefits of TCP: It helps you to establish/set up a connection between different types of computers. It operates independently of the operating system. It supports many routing-protocols. It enables the internetworking between the organizations. TCP/IP model has a highly scalable client-server architecture. It can be operated independently. Supports several routing protocols. It can be used to establish a connection between two computers. Disadvantages of TCP Here, are disadvantage of using TCP: TCP never conclude a transmission without all data in motion being explicitly asked. You can't use for broadcast or multicast transmission. TCP has no block boundaries, so you
