Cloud host is a technique where your files are stored on more than one computer meaning the load is spared among different server’s this will handle the load effieciently than a single server.
Following are the Cloud Host provider's
Google cloud basically provides all the services that one need to start cloud host not only that google offer’s one year free service with 200$ in account whichever last.
Hi, my name is kailash kumar. And this is an introduction to Google Cloud.In the next few minutes, we’re going to discuss what Google Cloud is and what some student developers have been able to create with it. Ready? We’re going to start by going back in time. Let’s pretend for a moment that we’re in the time before cloud computing, and we want to start a company to create a social networking site. You’d start by buying a server, lugging it all the way home from the store, and spending hours preparing it with all the correct hardware and software so it can run your company’s web app. Fast forward a few months, and things are looking up for your company’s site. The users are flooding in. As your organization’s user base grows, you have to buy and install more and more servers. This is called scaling. Eventually, you’re doing so well that the company opens up a data center. Next thing you know, you’re international and spending billions of dollars opening data centers all around the world. Sounds like a lot of work, right? Here’s the good news. You don’t have to do any of that. Luckily, some companies have spent years building some of the world’s most advanced networks of data centers. Cloud computing is when these companies allow developers to store data and run code on their computing infrastructure. Google is one of these companies. Google has data centers all around the world that have allowed it to scale to billions of users. These data centers house the computing infrastructure that powers the Google products you may be familiar with, such as Search, Gmail, and Google Photos. Google Cloud gives you the access to the same technology and infrastructure that powers Google. This means that Google Cloud has over 100 products and tools in categories like compute, storage, and machine learning and artificial intelligence that seamlessly integrate together all a click away. One category is compute. These products help you deploy code to the cloud. For example, we may use a compute product like App Engine to deploy a social networking site. Another category is storage and databases. These products help us store data, retrieve, and query data in the cloud. For example, we may want to store data for our dog walking app, the dogs’ names and locations, in a Cloud Firestore database. We also have machine learning and artificial intelligence. These products allow us to leverage Google’s AI technologies for our own applications. We can build and deploy our machine learning models to AI Platform or take advantage of one of the easy-to-use pre-trained machine learning APIs like Vision or Natural Language. So what is Google Cloud? In a sentence, Google Cloud lets developers build and host applications and websites, store data, and analyze data, all on Google’s scalable and reliable computing infrastructure.Firestore, a Google Cloud database, to store and sync user data. A team of student developers created a service called Nagish to help people who are deaf or hard of hearing talk on the phone. They leveraged Google Cloud’s Text-to-Speech and Speech-to-Text APIs to convert back and forth between voice and text. And that’s it. Let’s review. We started by talking about what Google Cloud is, a platform that lets developers build and host applications and websites, store data, and analyze data, all on Google’s scalable and reliable computing infrastructure.
2.AWS (Amzon Web Services)
what is AWS so guys AWS that is Amazon Web Services is a subsidiary of amazon.com as a world leader in cloud computing market right it was launched way back in 2006 when no company had the cloud computing business model it took the risk and now today 70% of the whole cloud computing market is residing on AWS so now you can imagine how big a the professor’s right talking about companies who are on AWS let’s look at some of the companies some of the prominent companies were using the AWS infrastructure so these are some of the very popular companies like Kellogg’s Robbie air B&B Chen electrics Netflix and Amazon which are using the AWS infrastructure for their operations now Netflix and Amazon are completely dependent upon the AWS infrastructure now you can imagine if these two companies which are so big and though the whole world is using it even your application is going to share the same infrastructure as these apps so you can imagine that your application is in safe hands right you can be assured with that having said that let’s move on to discuss but why do companies use AWS and what’s the advantage of having the cloud computing technology with you right so let’s shed a light on that and for that let’s take an example say you think of you know starting a business and say your business is you think of launching the Instagram application and you have the application ready now you have to make it available to the world so the first thing that you have to do is you have to invest some money buy some servers and upload your application on it and your application is up and ready right so you start with a small user base and you say ok so in one month or so I can expect that so-and-so users will be there but your plan doesn’t go according to your will and what happens in overnight your application becomes so viral that there are millions of users were trying to access your application now so the servers that you had and now very overburdened with the kind of traffic which is coming in and you get very anxious as to what to do so what you do you invest some more money by some more servers and now the situation seems to be a little normal right but guys servers are machines we should not forget about it right and they have bound to break down so one finally what happens is your servers they go down they go haver and your application is so to fix this again you had to hire a maintenance team which is now going to manage your servers for you that is anything kind of server upgrade which is required any kind of software up pass which has to be put in and when your server goes down replacing it with a new server all of that is now going to be managed by the maintenance team right so the kind of attention that was required for you to give to your application it could not get that attention because how are we our attention was towards the infrastructure side which is understandable right so these are the problems we folklore computing and one fine day the bills came up and said but why don’t you use my servers right I have a stack of servers in my warehouse why don’t you use some of them right and the best thing about it is that you know I you know how to bias the servers from me you can just rent them from me use them for the time you wanted to and give them any time you want say you give to me up to five hours you just pay for the five hours time that you used it for right at the same time you don’t have to worry about the maintenance right I will do the maintenance for my servers and with this this was like you know if the god came in and said let me help you it was like that so this was a very good deal for you because now you not spend money on buying servers and not spending money on the maintenance team everything is being managed by AWS and at a very cheap price of parada pieces right so it’s very awesome so moving forward we have understood why you know AWS companies are adopting AWS or any other cloud platform and what exactly is AWS it let’s move on to discuss the service with now so let’s take an example again here let’s take the example of a website so this is a skeleton architecture for a very normal web site that is there right how does it function the user first he goes onto a website he goes onto the internet and he types in a web address right that web address then goes to a DNS server that DNS server basically gets that converted into an IP address that IP address points to a load balancer that load balancer in turn is you know distributing the traffic among many of the servers and you end up on any one of these servers this is how it happens right and now this server is again connected to a relational database and this relational database is basically having all the information which is required for your website and also with these entities that is your database and your servers are inside a network so that they can communicate with each other right so these are the basic entities which are there in a cloud computing world right now taking the same problem as before that you know what suddenly a whole lot of user group comes in and your servers become overburdened now how do you take care of that so you don’t have to take care of anything cloud computing you know the cloud mobility model is herbs then it’ll take care of itself right so it automatically senses that you know the servers are getting overburdened it adds a solar automatically and now your situation becomes normal right so this is how the cloud computing board is going to help you out we discussed this already right but now having seen this architecture how it works now let’s look at how these services or how these components will look when you took it from the AWS perspective right so when you talk about AWS services the DNS server that we discussed is called route 53 this servers the web servers that we discussed our issue servers the relational databases are yes the network in which these components will be closed-in is BPC and the load balancer is again load balancer and the property which increases the number of servers and know is them according to traffic is auto-scaling right so these are some of the basic services offered by AWS and these are awesome values right so these were the services that we were to discuss moving forward now let’s discuss about the global infrastructure that AWS has to offer now AWS provides these many services throughout the globe it has a global presence right and these orange dots are the regions that AWS has right each region has multiple zones and zones are nothing but huge data centers with a lot of servers right so probably when you choose America when you choose the US so probably you will be ending here somewhere around here right if you choose the region 1 region is this and the other region is this one zone would be one circle and this is how it functions right so in all there are 18 geographical regions around the world and in those regions we have around 50 availability zones like I said a 50 huge stay the centers around the world that are at your disposal right but why will he need a global infrastructure is a question right so say let me take the same example forward the website servers and these servers are now distributed among different places throughout the world now what advantage does it give you first of all it helps in the disaster recovery kind of situation for example this server was done you all again have these two servers to solve your traffic flow right so this server goes on because of power outage or any natural calamity your application is still up because it has been hosted in different regions right this is one advantage the second advantage is that it serves the purpose of users from different countries for example you are in this country and in your trying to access your website probably you can access it from this server right rather than having your servers at one central location which will not only have more latency that is response line if a customer is out of the country but also it’s a very bad measure to take when we are too concerned about disaster recovery right so this is the reason that AWS has a global presence and they have a global infrastructure so it is there because so then your Chalmers can have the lowest latency possible and also you can implement the best is ask recovery measures all right having said that let’s now talk about AWS pricing there is now a double pricing is amazing so like we discussed so we have a per our billing kind of system right so and the pricing is also region specific in the sense that each region has different pricing for different services they don’t differ much but so they are different from each other for each region so you can choose a region according to your preference also there’s a scene called reserved instances so many choose reserved instances you save up to 90% costs so when you say reserve this a basically means you rent the server for a particular term say a one-year term or a three-year term and when you do that when you compare it with on-demand pricing you save up to 90% which is awesome right and also there is an option for spot pricing as well wherein you get incredibly low prices by bidding on servers for a particular price right so you’re bid on server for saying I want to sell for $2 if a server is available you get it right you use that server until the server price goes up and once it goes up the server is taken automatically for you right it could be helpful for workloads where in the work is not that urgent but you want to get it done in the minimum cost possible right so it is helpful with that and with that guys we come to an end to the AWS overview.
AWS is very old in this field as AWS is oldest cloud services provider prices are flexible and you can also try AWS lightsail which is new service from AWS as this provides fixed prices on server mind it you can upgrade server’s only from one to another means you can not expand only one thing like RAM or storage basically you need to configure from one server to another one on a fixed monthly pricing.
Hetzner cloud is a germany based company there server’s are very cheap as compare to AWS and google cloud you can use for Unbeatable value for money – optimised to scale. For individual applications, distributed systems, dynamic clusters or development environments.
