CLOUD PROVIDER

AWS - Amazon Web Services

Pioneer in Cloud computing, started with Amazon EC2 (compute) and Amazon S3 (storage) - IaaS. Now offers easy PaaS packaged services like Elastic Beanstalk. AWS has the longest catalog of Cloud services - Maximum flexbility for a developer

Google Cloud

Started off as a PaaS provider (GAE - Google App Engine), but now full fledged with IaaS as well (GCE - Google Compute Engine)

Heroku

An easy to use cloud provider (PaaS) which suits the needs of many web applications. Not exhaustive as AWS, but very popular as many applications can be realized here

Windows Azure

The cloud platform from Microsoft.

PROGRAMMING STACK

Python - with Flask, Django etc

A popular "batteries included" web programming paradigm.

Ruby - with Rails

Ruby with rails is very popular

Java - with Spring

Traditional web backend powerhouse, more popularly known as J2EE

Node.js

If you want to build the backend fully in JavaScript then here you go ! Very new, but fast trending.

CSS

LESS

Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.

SASS

Another popular CSS extension language, with a very good support in the form of Compass framework.

EMAIL

Marketing Email

Probably no form of marketing is as impactful as reaching an interested user in his mailbox. Mailchimp provides very good service here.

Transactional Email

These are the password-reset, purchase-confirmation kind of mails. Solutions like Mandrill helps to send such mails to your customers. An important requirement here is these mails has to be very realtime and not all email providers are capable of doing this.

Email Inbox

You have a web domain and possibly a website hosted. How do you receive emails on this domain (say like feedback@anotherstack.com) ? Typically domain registrars provide few Inboxes free. I would suggest using Google Apps for Business. You get the gmail experience. They charge a nominal annual fees (Per Inbox, not email id)

ERROR ANALYTICS

Backend Errors

Those errors/exceptions happening on your web backend. You need to know those are happenning to fix ! You also need info to fix it. NewRelic is a good service for this (though they provide lot more than this). You get alerted on errors and see nice graph on when what happend !

Javascript Errors

Erros happen in the browser (not just in the backend). These are mainly Javascript errors. Users might see somthing failing, you need to to fix them. There are services like errorception.com, Sentry etc which collects these errors and shows on a drashboard (also email alerts!) with stack trace.

Mobile App errors

Similar in severity to Javascript errors above. Services like Crashlytics do the similar job here. Crashlytics has a nice feature of collecting your recent logs as well and associating with the exception - makes debugging easier.

LOGS

Server Logs

Servers have lot of logs - you definitely needs to have! - for issue debugging or forensic analysis when things go wrong. We are living in cloud and there are multiple servers in the cluster. Each web request goes to the one which is less loaded. Which server do you look into when something goes wrong ? You need some service which aggregates all the logs and shows them together - with good search capabilities. Services like Splunk and Loggly helps to do this.

USAGE ANALYTICS

Google Analytics

The popular free analytics service from Google. Very easy to use.

Adobe Analytics

Earlier known as Omniture Sitecatalyst. This is a paid product, but very feature rich. One great benefit is the possibility of getting raw data feed - important if you want to connect the analytics data to your service's backend - Beyond just reporting

Kissmetrics

Relatively new player - Paid product with pay as you go pricing. Since they focus ONLY on analytics, expect great detailing and agility
