    Uses for FTP that you may not know about

    FTP is one of the protocols that are a lot popular. Moreover, it has been around since 1971​. In present days, it could be implemented in some interesting situations. So, let’s take a minute to explain a little bit more about it.

    FTP (File Transfer Protocol) explained.

    File Transfer Protocol, or just FTP for short, is a standard communications protocol used to transfer files between devices over a network. In addition, the two have a TCP/IP (Internet) connection. As a network protocol connecting a user and a server, FTP gives the ability for users to download different files, pages, or programs which are available on other services. When the user requires to download the data to their personal device, they are utilizing FTP.

    It is important to note that FTP does not apply encryption. For the purpose of authentication, it only relies on cleartext usernames and passwords. Unfortunately, that makes the transference of information sent with FTP defenseless to common practices of impersonation and other types of attacks.Yet, there is SFTP (Secure File Transfer Protocol) which is able to provide secure transfer of files.

    ​What are the advantages?

    • It provides schedule transfers. 
    • With FTP, you are able to transfer very large files.
    • It is possible to renew an interrupted FTP connection.
    • With it, you are able to send several directories with files at the same time. That way, you speed up the transfer process a lot.

    ​When to use it?

    • It is common to use File Transfer Protocol to download big files over the Internet.
    • It is possible to use it for uploading an extensive file to your web hosting.
    • It is a great option when you want to make a backup of your website.

    Interesting uses of FTP

    1. You can collect data for connected devices – The number of IoT devices is increasing, and all of the machines are connected to the Internet, like laptops, computers, tablets. You can get all of the data and transfer it over a wireless network without the need for human interaction. By setting up automated FTP transfers, the data transfers regularly. 
    2. Content distribution network (CDN) – Large media content organizations and different radio and TV shows require quick and stable data transfer. That way they achieve shows to air on time. The ability of FTP to carry huge amounts of data is a benefit for them. 
    3. E-commerce business – Online shopping is great, and it has a lot of benefits. Yet, there is a lot of stuff happening behind the scenes. Secure File Transfer Protocol (SFTP) assists e-commerce companies by transferring the information to different essential for the company systems, like analytics. That way, the organization can keep moving forward.
    4. Third-Party Logistics (3PL) – We all desire things to happen as fast as possible. A lot of 3PL services utilize secure FTP for sending packages and transaction data. In addition, they have to share information fast and keep the order fulfillment correct.
    5. Mars Roving – Due to its reliability, one of the most critical photographs of a generation was trusted for transfer through FTP. It was set up as an automated process to send images from Mars to Earth. The File Transfer Protocol was capable of handling it.

    Load balancing for efficient traffic management

    What is load balancing?

    Load balancing is a great and very commonly used method implemented for managing the traffic of a hostname. With it, you are able to effectively and in a coordinated way to spread the incoming network or application traffic through a number of servers.

    If you own and maintain a website with a lot of popularity, that definitely means your website is going to receive massive traffic daily. In addition, it has to be able to operate with a large number of receiving requests from the users. Also, for every request has to be provided an answer that is right and with the exact part of the information, like text, picture, video, or application data. The whole process has to be performed in the quickest and safest way.

    First, the load balancers are going to implement several criteria and examine the incoming traffic. Next, as the following step, they decide and decide to let the traffic proceed or, in a different case, to prevent it from continuing. They could redirect it to a separate server based on the load of packets at the moment or other parameters. 

    How does load balancing work?

    The usual order of how load balancing work looks like:

    1. Traffic comes to your website. Users send many requests to your website’s server through the Internet.
    2. The traffic is spread over the server resources. The load balancer receives every request and guides it to a suitable server.
    3. Every server works with a reasonable workload. The server gets the request and is able to approve it. Then it returns an answer to the balancer if it is not overwhelmed with an extreme amount of requests.
    4. The server replies to the query. The process is performed in backward order to transfer the server’s reply back to the user.

    Types of Load Balancers

    The load balancer manages the upcoming traffic, and it could arrange it depending on:

    • When was the arrival of the query? – This method is a very simple and popular way to balance the traffic. Every query goes to a different server, depending on the time it arrives. For illustration, request one proceeds to server one, request two goes to server two, and so on. It starts all over, after that. 
    • What is the location of the query? – In that case, the load balancer recognizes from where the traffic is appearing. Next, it redirects it to a specific IP address that is going to provide a quicker answer and better performance. The perfect example of this type is GeoDNS. 
    • Is the server busy? – A wise way to manage the traffic is to base it on the occupation of the servers. The queries are going to move to the next most nearby server in a case when the primary server is overloaded. The network will continue to operate efficiently.
    • Weighted balancing – You could choose what value to be based on. It defines which server should, and it is able to receive more traffic. For instance, such value could be the server’s computing power.
