I used to develop app with classical hosting, let's say we have an MVC app running a MySQL database hosted in a classical hosting company like Godaddy
My question is : My application seems very fast, and managing well concurrent connections, but will grow probably exponentially. So I am wondering if keeping my application layers (app files) on Godaddy and moving the database on the cloud like Amazon-RDS is possible. And if possible will it make my app faster than it is.
It is defintely possible, but might not be the best solution: it depends on wether or not you are having a latency problem or a database query performance issue. Using aws to host MySQL gives you almost unlimited ability to scale up the performance of your db operations, but if that is not the bottleneck, it won't do you much good. Hosting the web on godaddy and db on aws will introduce additional latency between the web and the db.
Personally, if you are thinking of moving Part of your stack to aws, you might as well move the web layer as well -you'll get fast and scalable db performance with none of the additional latency cause by use both hosts and disparate locations.
I recommend you to deploy your web application on the same infrastructure where you are going to use your MySQL database. Amazon RDS provides you a great way where you can scale up or down your MySQL database. As far as I know, the hosting provider that you mention has its own infrastructure, so I would deploy your application on the same Amazon datacenter.
However, you have more options than using AWS, as there are some PaaS (Plarform as a Service) which use Amazon as an IaaS. The benefit of using a PaaS is that you can scale up or down your application in the same way that you are thinking about your MySQL database.

Quick bit of advice if i may. I'm a startup company and developing a new mobile app that i intend to query and update data from a cloud MYSQL database, using a restful webservice and JSON. I am pretty new to this, but ok on the theory.
I originally thought i could use Dropbox to host the database and somehow install a Tomcat server also, to act as the http server, but i cant find anything online that says this is achievable. I've now found a temporary site heliohost.org, which offers free hosting, so i'm looking into that.
Does anyone have advice on a [low cost] longer term production cloud service for MYSQL database? And am i right that a good approach is to create a restful webservice in Eclipse and then somehow deploy that to the Tomcat server in the cloud, so that my app can then issue calls to it via the CN1 available methods.
There is quite a lot out there and much of it is self-promoting their own sites so was after some independent advice please.
Many thanks in advance.
You can't host and access an SQL server over the network from a device as access is remarkably unreliable and insecure. You will need some form of hosting. I used Linode for our online course since they are very affordable (5USD per month) but I've used AWS, Digital Ocean and others. They are all good.
You are correct that you will need to create a webservice, I used tomcat in the past but for the latest course I chose SpingBoot which is easier and more modern.
Using a mobile backend to store and retrieve data is a vast topic to discuss where different tools and services can be leveraged based on your application use cases.
However directly accessing MySQL server from your mobile client wouldn't be a recommended approach both in term of security as well as performance at scale.
Few options you can consider.
Developing the mobile backend with Amazon Mobile Hub where you can find different architectures and services. For example.
Using AWS DynamoDB as a Mobile Backend tightly controlling access permissions with AWS Cognito and DynamoDB Fine Grained Access Control.
Using Cognito Sync as a storage medium to Synchronize data from Mobile App to AWS and then using triggers to share and push data & etc.
Developing a REST API for the mobile backend using AWS Services such as API Gateway, Lambda & DynamoDB(Or Relational Databases like MySQL, Postgres SQL & etc. with RDS)
From what I gather, the only way to use a MySQL database with Azure websites is to use Cleardb but can I install MySQL on VMs provided in Azure Cloud Services. And if so how?
This question might get closed and moved to ServerFault (where it really belongs). That said: ClearDB provides MySQL-as-a-Service in Azure. It has nothing to do with what you can install in your own Virtual Machines. You can absolutely do a VM-based MySQL install (or any other database engine that you can install on Linux or Windows). In fact, the Azure portal even has a tutorial for a MySQL installation on OpenSUSE.
If you're referring to installing in web/worker roles: This simply isn't a good fit for database engines, due to:
the need to completely script/automate the install with zero interaction (which might take a long time). This includes all necessary software being downloaded/installed to the vm images every time a new instance is spun up.
the likely inability for a database cluster to cope with arbitrary scale-out (the typical use case for web/worker roles). Database clusters may or may not work well when a scale-out occurs (adding an additional vm). Same thing when scaling in (removing a vm).
less-optimal attached-storage configuration
inability to use Linux VMs
So, assuming you're still ok with Virtual Machines (vs stateless Cloud Service vm's): You'll need to carefully plan your deployment, with decisions such as:
Distro (Ubuntu, CentOS, etc). Azure-supported Linux distro list here
Selecting proper VM size (the DS series provide SSD attached disk support; the G series scale to 448GB RAM)
Azure Storage attached disks being non-Premium or Premium (premium disks are SSD-backed, durable disks scaling to 1TB/5000 IOPS per disk, up to 32 disks per VM depending on VM size)
Virtual network configuration (for multi-node cluster)
Accessibility of database cluster (whether your app is in the vnet or accesses it through a public endpoint; and if the latter, setting up ACL's)
Backup / HA / DR planning
Someone else mentioned using a pre-built VM image from VM Depot. Just realize that, if you go that route, you're relying on someone else to configure the database engine install for you. This may or may not be optimal for what you're trying to achieve. And the images may or may not be up-to-date with the latest versions, patches, etc.
Of course, what I wrote applies to any database engine you install in your own virtual machines, where a service provider (such as ClearDB) tends to take care of most of these things for you.
If you are talking about standard VMs then you can use a pre-built images on VMDepot for that.
If you are talking about web or worker roles (PaaS) I wouldn't recommend it, but if you really want to you could. You would need to fully script the install of the solution on the host. The only downside (and it's a big one) you would have would be the that the host will be moved to a new host at some point which would mean your MySQL data files would be lost - if you backed up frequently and were happy to lose some data then this option may work for you.
I think, that the main question is "what You want to achieve?". As I see, You want to use PaaS solution with Web Apps or Cloud Service and You need a MySQL database. If Yes, You have two options (both technically as David Makogon said). First one is to deploy Your own (one) server with MySQL and connect to it from the outside (internet side). Second solution is to create one MySQL server or cluster and connect Your application internally in Azure virtual network. WIth Cloud Service it is simple but with Web App it is not. You must create VPN gateway in Azure VM and connect Your Web App to this gateway. In this way You will have internal connection wfrom Your application to Your own MySQL cluster.
Simple question can a Java service layer running on Tomcat7 on a host machine connect to persistent data store (mySQL) running inside a virtual box with portforwarding? I want to know if the hibernate or Jdbc connection strings from host machine work if mySQL server is installed inside a VirtualBox.
Also if it does work can I expect behavioral deviations in terms of speed and connection pooling if everything is packaged into one single system and deployed in a real world web server in a single enviroment?
The short answer is yes, it is possible and will work. You will likely have to play with the firewall settings on your virtual box instance. You don't specify OS, so it's hard to tell you what exactly you'll need to tweak.
As far as deploying this in a real-world environment, if you mean production, you probably should NOT do that. This is a great setup to build on, but not something I would run in production.
To be clear, there won't be any issues behaviorally speaking, it will act as MySQL always acts, but it will absolutely be slower than running it on 'bare metal' -- how much slower will vary based on hardware, workload, etc. and it is generally not a great design for a production deployment..
I have a dedicated server with WHM and cPanel installed on it.
recently I decided to move to cloud services since the dedicated server is costly and I'm not actually using any of its power, freedom and functionality.
I was considering moving to AWS or Heroku since they are less expensive, scalable and I don't need to manage the server myself.
I only have few websites on my server and I'm managing them via cPanel and WHM
I'm only using mySql database
I have also have some cron jobs setup
I use ftp to upload and maintain my websites (no git)
I was wondering if anyone could explain how I can transfer my files, databases, and domains to either AWS or Heroku.
I prefer the one that is easier and faster to migrate to.
Thanks.
If server/network management is not your strength, I would strongly advise against using AWS (even as big a proponent of AWS as I am). You absolutely must manage the servers yourselves, at least the configuration aspect (not the hardware aspect). In fact, you will find that you have to do things like set up security policies, identity access management, IP addresses, etc. that are not always that intuitive to one who is not used to working in a bit of an operations capacity.
You will also likely have to consider application architecture changes to work best with AWS services. Additionally, you will have to become accustomed to the AWS way of doings things (that starting and stopping server instances may make all your data go away and such).
If you are looking for a hands-off server approach, you might be better served looking at something like Slicehost/Rackspace.
I can't talk much to Heroku as I have only minimal experience prototyping on it. You can think of it more as an application platform. For simple applications that don't have unique traffic demands or architectural requirements, it seems a good solution for getting an application up and running with minimal server-related configuration. Again a legacy app will probably require some re-architecting to do things the Heroku way.
AWS are good but the support at Rackspace is far better and much more suited for someone like you. Rackspaces support is 24/7 and even on their online chat system you don't need to wait more than a few mins to speak to someone who actually knows what they are doing.
I have developed several websites on my local host for school. I can program database driven aspects of a webisite such as a blog on my own no problem. At school I used a MySQL DB which was hosted on a dedicated server, so when the server went down I could not have access to my data. I also have a mysql DB on my localhost but...my question is this: If i use the MySQL DB on my localhost, won't I only have access to the data when my computer is running so that my site can make server requests?
How can I set up any kind of DB for my site that is reliable and doesn't depend on my localhost to act as a DB Server?
I am now developing in .NET
Thanks. PS I don't have access to schools' server any more.
PPS I still don't have a site set up through a hosting provider...probalby going to go with godaddy
You'll need a server for that. A server will cost you on a monthly basis, I haven't heard of any free mysql servers, someone else may be able to help you with that.
Regular hosting providers supply PHP and MySQL server. I run my sites on Dreamhost (www.dreamhost.com)
It might also be worthwhile to look into Amazon EC2 : http://aws.amazon.com/ec2/
Also Amazon RDS for pure database only usage : http://aws.amazon.com/rds/
They provide a pay as you use service and the tier 1 service is free for the first year as I understand
There's no magic, you have to host your DB on a server that will run 24/7. Could be on the internet, it depends on the firewalls surrounding you.
The website will always depend on some sort of database server, why so worried that your database will be unreachable? Your webserver can go down also and will have the same consequences as the db.
Why don't you get some paid hosting? It is fairly cheap these days, for around 30dollar/year you will have some reliable hosting. When the DB will break down, it is not your responsibility.
If you don't want te be dependent of MySQL, you will need to use plain-text database that will be maintained by PHP or something.
You might consider running the MYSQL in i.e. a cloud provider, like Amazon EC2. It will certainly cost some money.
