I have no experience with VPS's. Over the past year or two I've been getting more and more into web development, as a hobby and for work. I'm currently managing one wordpress site, a codeigniter app, a node.js/mongodb app, and various other personal projects. They are currently all hosted seperately (misc LAMP hosting, heroku, etc.).
I'm looking for a solution that will enable me to do the following:
Host Static/PHP Sites/Apps (so a LAMP stack)
Node.js/MongoDB/Redis
capable of other stacks (django/yesod/RoR/etc.)
Would a Linode VPS be capable of handling all of this? None of these sites get large amounts of traffic. The web apps are private, business management apps, used by 2-10 people at a time. The public sites are small business websites and my portfolio. I would like to be able to host future work on the same VPS as well (same types of small sites/apps).
I have no experience managing multiple domains on the same server. Is this easily done (or possible) with a single Linode VPS?
EDIT
I'm looking at the Linode 512MB/1GB VPS's, $20/$40 respectively.
Of course.
Especially after the massive Linode NextGen upgrades, a Linode VPS can easily handle this kind of workload. Since it's a VPS and not merely shared hosting, you get root access and therefore full control over the system.
In addition, Linode includes features such as advanced disk image management that allows you to clone and resize disk images as required and quickly boot into different images, as well as an out-of-band shell that allows direct access to the server's console in the event you cannot access it via SSH. A Linode 1024 (1GB) plan is more than enough for this sort of workload.
There are lots of different VPS providers out there. Rackspace is very expensive but probably has the highest level of reliability (100% uptime SLA with 5% refund per 30 minutes downtime) and outstanding "Fanatical Support". For less critical needs, there are loads of smaller VPS providers that offer cheap rates, but often with only minimal resources and fewer features. Some provide super-fast SSD storage for disk-intensive applications. You should shop around and do your research so that you find a VPS provider that meets your requirements.
I suggest that you may look into a shared hoisting plan on a reputed hosting companies like hostgator since there isn't much traffic.I also suggest you also buy a cpanel for managing tools.Cpanel has a web interface with which you can control every tool using your mouse & keyboard.
On the other hand linode has a CLI interface and their support expects you to have some descent knowledge about managing VPS servers.

I many articles where writers show how to deploy a Laravel app/website on shared hosting they discourage doing that. In some other quora questions where the answers state that it is possible but has some security risks. So what security risks does this practice implies.
The honest answer depends on the type of project and-or customer (agency vs interprise).
If you are working for a smaller project and there is no on-going development (extra possible invoicing) to it I will recommend using a shared hosting.
But if your budget is pretty high and that application needs to grow, handles sensitive user data, automated deployments, unit testing together with Docker and Vagrant for local development. I would recommend using AWS or digital ocean.
The biggest problem using AWS is that it pushes the responsibility to you in keeping the operating system and PHP-version up-to-date.
With interprise customers, I would recommend using services like:
Use a security scan (https://detectify.com/)
Use a Firewall (https://www.cloudflare.com/en-gb/)
Basically it all depends on the type of customer you are dealing with.
But for a really small / tiny projects, just use a shared hosting and basically never forget to use CSRF, ReCaptcha, throttling requests, ... Be smart about it.
I'm thinking of moving about 5 websites over to be hosted on Github pages from a dedicated host. They will all be converted to static websites. The domain names will still be managed there, what are some options for email hosting cheaply or at all?
I've always gone with Google's G Suite.
The basic plan gives 30GB of storage, and costs $5/User/Month
The business plan gives Unlimited storage, a few more features, and costs $10/User/Month
There's also an enterprise plan, but I don't think you'd need it.
I have a project and I'm planning to start the web app as an Azure Web Site and then migrate it to an Azure Cloud Service (also called Hosted Service) if it is needed as a scale strategy.
The decision is because I read that Azure Web Sites are more simple and fast to develop with almost no Azure-specific configurations or code. So starting fast and simple is a good starting point for the project.
But, is that a good starting point for you?
Is migrating an Azure Web Site to an Azure Cloud Service the same as you were migrating a normal ASP.NET Website to an Azure Cloud Service?
Would you start with an Azure Cloud Service right from the beginning? If yes, why?
Thanks for your time.
There are benefits to both deployment models, it will eventually come down to what you are trying to achieve and ultimately the success of your application.
Below I've outlined the Pros and Cons of each of the models to ensure that you're making the right choice for your applications goals.
Windows Azure Web Sites
You have properly identified that Windows Azure Web Sites is a great starting point for an application, however you could also consider that Web Sites does offer enough scalability for many solutions.
Pros
10 Free sites during preview [Free for 12 months]
Easy Deployment (use Git, TFS, Web Deploy or FTP)
Quick Scalability (You can move to your own dedicated cluster [aka reserved standard])
Simple Development (Supports Classic ASP, ASP.NET, Node.js, Python & PHP)
Persistent Environment (most people are used to this)
Cons
No SSL Support on Custom Domains
in Preview (currently no SLA)
Windows Azure Cloud Services
Cloud Services (formerly known as Hosted Services) is definitely the vision for the future of Web Applications. It is built with resiliency in mind to keep the cost of applications affordable by scaling to meet demand, and dial back capacity when your traffic slows.
Pros
Increased control over the cost of your application (if architected correctly)
Flexibility (You have full control over the environment)
SSL Support
Language Agnostic
Web Server Agnostic (although IIS is available by default)
Auto Management of Servers
Cons
Architecture should be carefully considered
Deployment time is slower (Slows development cycle)
Things to consider for Portability
The items above might have given you enough to plan the immediate future of the application and it is very likely that you might want to consider Cloud Services in the future (it fits a number of application scenarios better in the long run).
Here is a list of things to help portability between Web Sites to Cloud Services:
Start thinking Stateless
Windows Azure Web Sites is nice as it is a persistent environment, which means you are able to store things like session state and assets to the disk.
Although this is a good feature, it's best to start planning towards a stateless application, if your end goal is to be in Cloud Services. Here are a few things you can do to start thinking stateless:
Don't rely on Session State
If you need it, come up with a strategy to make it scale (Caching Service, SQL, or Storage)
Use the Storage Service
Assets such as Static HTML, css, javascript and images are better placed in Storage
Avoids additional bandwidth on your Web Site (potentially stay shared longer for lower cost)
Can be CDN Enabled, provides a better experience for International markets
Easier to update web assets when application is migrated to Cloud Services
Storing User content
If your application already stores to the Storage Service, there is one less code modification in the future when moving to cloud services.
Make it easy to discover patterns in your Data
The benefit of Cloud Services is it enables you to reduce cost by only scaling what needs scaled. Starting the process of identifying your scale units i.e. How you partition your database or Tables in Storage.
I read all post and all of them are very helpful.
In addition to all post , I found an info on msdn : Windows Azure Websites, Cloud Services, and VMs: When to use which?
With Windows Azure Websites you can:
Build highly scalable web sites on Windows Azure.
Quickly and easily deploy sites to a highly scalable cloud environment that allows you to start small and scale as needed.
Use the languages and open source applications of your choice then deploy with FTP, Git or TFS, and easily integrate Windows Azure services like SQL Database, Caching, CDN and Storage.
With Cloud Services you can:
Build or extend your enterprise applications on Windows Azure.
Create highly-available, scalable applications and services using a rich PaaS environment. Support advanced multi-tier scenarios, automated deployments and elastic scale. Deliver great SaaS solutions to customers anywhere around the world.
And also there is summarizes the option on msdn :
And comparing some features Web Sites and Cloud Services on msdn:
Azure is a great place to have your app, but there are some considerations you need to know before start migrating it.
Azure Websites and Hosted Services are really trivial to deploy. With
Visual studio you generate the package and simply upload it. Then you
have a Development environment to check it. If it's ok for you, swap
ips. If it's not ok for you, upgrade again.
Your instances have some properties that could be annoying. For
example, you cannot be sure about your IP. Then if your app works
with some provider using IP restriction, you will need to figure out
how to proceed.
More considerations. Your "server" could be reimaged at any moment.
If you store something on the local disc, that file could go away at any moment.
Azure works very nice if you have at least 2 instances or more for
each website. Maybe your app is not prepared for that. The first step
will be managing the sessions with the appFabric. Is really
easy, just a change on your web config. Be careful because this
session state doesn't work exactly as the "old one". You cannot store
non-serializable objects (should be easy to adapt) or a very large objects (more than 8MB).
If you are going to develop something from zero, I suggest you to start into azure from the beginning. The reason is simple: it's really cheap to start and you will not pay serious money until the app have lot's of visits. It's also very cheap to setup a SQLAzure and a storage account. One you have all in place, it's easy to add more instances or scale up.
Example:
Imagine you have an idea and you wish to show up to some possible investors.
You start setting up a little SQLAzure database (1GB ), $9,99 monthly.
Then you build a site and you put 2 extra small instances, $18,72 monthly.
Let's say you need 100 GB of space (images, backups, ...), $12,50 monthly.
At his point, you have all in place to start your business paying less than $50 monthly.
If you site have exit and the visits starts to come, you change your instances for small instances (it's really dangerous to have production environment with extra small instances, because do not have cpu reservation). Then you change the extra small cost ($18,71) up to $57,60. Maybe you need more space to that SQL Azure? etc...
prices calculated from here: http://www.windowsazure.com/en-us/pricing/calculator/?scenario=web .
Those are few tips, there is a lot more. My advice is to start a trial account and play with it.
Final advice: Its very easy to solve everything just purchasing more resources. Sometimes you need to refactor and optimize your code. If you simply add more resources each time you have a problem, you could end with a huge bill and a very messy code.
Hope it helps!
Another advantage of Windows Azure Cloud Services over Web Sites is that a cloud service can be added to an Azure Virtual Network. This can give it access to on-premises resources like databases. So if your requirements are such that you need the scalability offered by Azure but need to keep your data on-premises due to security restrictions, cloud services is a better choice.
Azure web sites cannot be part of an Azure virtual network. To access on-premises resources mechanisms such as Azure Service Bus Relay must be configured.
We've had our web site running on PHP on some hosting and at some point decided to move it to Azure (where sits main part of our service). We've started with Azure Web Sites which was great from development point of view (mainly integration with git). But after about a week of testing (when we've decided to actually move the production web site) we've found that currently
No SSL for custom domains
Custom domains are available only for reserved instances (no shared infrastructure)
SLA
So we moved to Hosted Service. The main problem for us was lack of ability of simple deployment (need to build package and upload whole package of the web site), and found solution was to use dropbox - as a startup task for role, we're installing dropbox service on the machine, which takes all the web site from dropbox, which in turn have SVN checked out folder, so site updates became very easy.
What are the pros and cons of using dedicated servers versus Aamzon EC2 for hosting a high traffic website - that has about 2 million visitors and 5 million page views a month. The content is mostly dynamic and served from a database. Does anyone has any experience of the costs and performance for such a setup.
Amazon EC2 is going to be much more cost-effective versus dedicated servers from my experience. Should you experience a sudden rise in the volume of traffic to your site all you need to do is shell out some extra $$ to Amazon and voila your site can handle the traffic (assuming there are no coding bottlenecks). Unless you have a truly massive website (ie: Facebook) the benefits of hosting on Amazon EC2 far outweigh the risks.
One of the only risks that you take with hosting on EC2 was showcased a few months ago when the whole cloud went down, taking Foursquare, Quorra, Reddit, and other multi-million user base sites down along with it.
From a user experience I believe interaction with the cloud hosting provider is pretty much the same as interacting with a dedicated server, so the only real concern to take into account would be cost-effectiveness.
My own experience tells me that at least in this part of the world, New Zealand, where we don't yet have a local amazon server farm, Amazon provides poor performance and is one of the most expensive options for hosting busy websites. I placed some background on my blog that goes through my own experiences. http://www.printnet.co.nz/category/hosting/

I have thought a lot recently about the different hosting types that are available out there. We can get pretty decent latency (average) from an EC2 instance in Europe (we're situated in Sweden) and the cost is pretty good. Obviously, the possibility of scaling up and down instances is amazing for us that's in a really expansive phase right now.
From a logical perspective, I also believe that Amazon probably can provide better availability and stability than most hosting companies on the market. Probably it will also outweigh the need of having a phone number to dial when we wonder anything and force us to google the things by ourselves :)
So, what should we be concerned about if we were about to run our web server on EC2? What are the pro's and cons?
To clarify, we will run a pretty standard LAMP configuration with memcached added probably.
Thanks
So, what should we be concerned about if we were about to run our web server on EC2? What are the pro's and cons?
The pros and cons of EC2 are somewhat dependent on your business. Below is a list of issues that I believe affect large organizations:
Separation of duties Your existing company probably has separate networking and server operations teams. With EC2 it may be difficult to separate these concerns. ie. The guy defining your Security Groups (firewall) is probably the same person who can spin up servers.
Home access to your servers Corporate environments are usually administered on-premise or through a Virtual Private Network (VPN) with two-factor authentication. Administrators with access to your EC2 control panel can likely make changes to your environment from home. Note further that your EC2 access keys/accounts may remain available to people who leave or get fired from your company, making home access an even bigger problem...
Difficulty in validating security Some security controls may inadvertently become weak. Within your premises you can be 99% certain that all servers are behind a firewall that restricts any admin access from outside your premises. When you're in the cloud it's a lot more difficult to ensure such controls are in place for all your systems.
Appliances and specialized tools do not go in the cloud Specialized tools cannot go into the cloud. This may impact your security posture. For example, you may have some sort of network intrusion detection appliances sitting in front of on-premise servers, and you will not be able to move these into the cloud.
Legislation and Regulations I am not sure about regulations in your country, but you should be aware of cross-border issues. For example, running European systems on American EC2 soil may open your up to Patriot Act regulations. If you're dealing with credit card numbers or personally identifiable information then you may also have various issues to deal with if infrastructure is outside of your organization.
Organizational processes Who has access to EC2 and what can they do? Can someone spin up an Extra Large machine and install their own software? (Side note: Our company http://LabSlice.com actually adds policies to stop this from happening). How do you backup and restore data? Will you start replicating processes within your company simply because you've got a separate cloud infrastructure?
Auditing challenges Any auditing activities that you normally undertake may be complicated if data is in the cloud. A good example is PCI -- Can you actually always prove data is within your control if it's hosted outside of your environment somewhere in the ether?
Public/private connectivity is a challenge Do you ever need to mix data between your public and private environments? It can become a challenge to send data between these two environments, and to do so securely.
Monitoring and logging You will likely have central systems monitoring your internal environment and collecting logs from your servers. Will you be able to achieve the monitoring and log collection activities if you run servers off-premise?
Penetration testing Some companies run periodic penetration testing activities directly on public infrastructure. I may be mistaken, but I think that running pen testing against Amazon infrastructure is against their contract (which make sense, as they would only see public hacking activity against infrastructure they own).
I believe that EC2 is definitely a good idea for small/medium businesses. They are rarely encumbered by the above issues, and usually Amazon can offer better services than an SMB could achieve themselves. For large organizations EC2 can obviously raise some concerns and issues that are not easily dealt with.

The main negative is that you are fully responsible for ALL server administration. Such as : Security patches, Firewall, Backup, server configuration and optimization.
Amazon will not provide you with any OS or higher level support.
If you would be FULLY comfortable running your own hardware then it can be a great cost savings.
i work in a company and we are hosting with amazon ec2, we are running one high cpu instance and two small instances.
i won't say amazon ec2 is good or bad but just will give you a list of experiences of time
reliability: bad. they have a lot of outages. only segments mostly but yeah...
cost: expensive. its cloud computing and not server hosting! a friend works in a company and they do complex calculations that every day have to be finished at a certain time sharp and the calculation time depends on the amount of data they get... they run some servers themselves and if it gets scarce, they kick in a bunch of ec2's.
thats the perfect use case but if you run a server 24/7 anways, you are better of with a dedicated rootserver
a dedicated root server will give you as well better performance. e.g. disk reads will be faster as it has a local disk!
traffic is expensive too
support: good and fast and flexible, thats definately very ok.
we had a big launch of a product and had a lot of press stuff going on and there were problems with the reverse dns for email sending. the amazon guys got them set up all ripe conform and nice in not time.
amazon s3 hosting service is nice too, if you need it
in europe i would suggest going for a german hosting provider, they have very good connectivity as well.
for example here:
http://www.hetzner.de/de/hosting/produkte_rootserver/eq4/
http://www.ovh.de/produkte/superplan_mini.xml
http://www.server4you.de/root-server/server-details.php?products=0
http://www.hosteurope.de/produkt/Dedicated-Server-Linux-L
http://www.klein-edv.de/rootserver.php
i have hosted with all of them and made good experiences. the best was definately hosteurope, but they are a bit more expensive.
i ran a CDN and had like 40 servers for two years there and never experienced ANY outage on ANY of them.
amazon had 3 outages in the last two months on our segments.
One minus that forced me to move away from Amazon EC2:
spamhaus.org lists whole Amazon EC2 block on the Policy Block List (PBL)
This means that all mail servers using spamhaus.org will report "blocked using zen.dnsbl" in your /var/log/mail.info when sending email.
The server I run uses email to register and reset passwords for users; this does not work any more.
Read more about it at Spamhaus: http://www.spamhaus.org/pbl/query/PBL361340
Summary: Need to send email? Do not use Amazon EC2.
The other con no one has mentioned:
With a stock EC2 server, if an instance goes down, it "goes away." Any information on the local disk is gone, and gone forever. You have the added responsibility of ensuring that any information you want to survive a server restart is persisted off of the EC2 instance (into S3, RDS, EBS, or some other off-server service).
I haven't tried Amazon EC2 in production, but I understand the appeal of it. My main issue with EC2 is that while it does provide a great and affordable way to move all the blinking lights in your server room to the cloud, they don't provide you with a higher level architecture to scale your application as demand increases. That is all left to you to figure out on your own.
This is not an issue for more experienced shops that can maintain all the needed infrastructure by themselves, but I think smaller shops are better served by something more along the lines of Microsoft's Azure or Google's AppEngine: Platforms that enforce constraints on your architecture in return for one-click scalability when you need it.
And I think the importance of quality support cannot be underestimated. Look at the BitBucket blog. It seems that for a while there every other post was about the downtime they had and the long hours it took for Amazon to get back to them with a resolution to their issues.
Compare that to Github, which uses the Rackspace cloud hosting service. I don't use Github, but I understand that they also have their share of downtime. Yet it doesn't seem that any of that downtime is attributed to Rackspace's slow customer support.
Two big pluses come to mind:
1) Cost - With Amazon EC2 you only pay for what you use and the prices are hard to beat. Being able to scale up quickly to meet demands and then later scale down and "return" the unneeded capacity is a huge win depending on your needs / use case.
2) Integration with other Amazon web services - this advantage is often overlooked. Having integration with Amazon SimpleDB or Amazon Relational Data Store means that your data can live separate from the computing power that EC2 provides. This is a huge win that sets EC2 apart from others.
Amazon cloud monitoring service and support is charged extra - the first one is quite useful and you should consider that and the second one too if your app is mission critical.
