How To Set a VPN on Google Compute Engine

There are many cases where you wish to migrate data from one location to another. In most cases, you will wish to do it over a secure channel. In this tutorial we will see what are the main steps in order to set a VPN (in this case: StrongSwan) on Google Compute Engine so you will have a server to server VPN solution between your on premiss server(s) and GCE. In this tutorial we will setup a VPN connection from your own datacenter to Googjle Compute Engine. First, let’s look at the big picture. We wish to have one gateway in our datacenter and another on Google Compute Engine. These gateways, will be responsible to connect and secure our channel so we could transfer our data over it in a secure way.

Chrome And HTML5 Updates

There are some very interesting technologies that are now available in Chrome. In this post I will try to cover some of them.

We know that Google started the Chrome project on the three ideas of speed, simplicity, and security. It’s still focusing on these important aspects while keep moving forward (fast) on implementation of many other HTML5 features. You can find Chrome on mobile, desktop, Chromebook and Chromecast. Let’s see what are the new, improved features we got these days as developers in Chrome platform:

Focus areas Chrome is moving forward

Mobile and Open Web Platform

We’re investing a lot of time to make sure mobile web experiences improve and that they are easier to develop!

  1. Build amazing mobile web apps
  2. WebGL, Web Audio, WebRTC, Web Speech and many more APIs that give you ‘native’ capabilities inside your browser.
  3. Vibration
  4. Device Motion
  5. WebRTC code lab (link) to check the new world of media (video/audio) in Chrome without plugins.

Big Query Basics

Big QueryIn today talk, I’ve covered one of the coolest tools in the “big data” world – Big Query. What is BigQuery? Well, querying massive datasets can be time consuming and expensive without the right hardware and infrastructure. BigQuery solves this problem by enabling super-fast, SQL-like queries, using the processing power of Google’s infrastructure. If you wish to play with a cool a BQ demo, just click on the picture on the left.

When to use it?

There are few bold use cases in the analytic landscape that Big Query is the right tool for the job:

  • It’s a great option when your MapReduce based analysis (=Hadoop system) can be slow for ad-hoc queries.
  • If you don’t wish to manage large data centers and tuning Hadoop all day long.
  • It seems that analytics tools should be services at 2014, no? Continue reading

Google Cloud Storage Migration, Backup, and Archive

Google cloud storageToday we covered Google Cloud Storage. Google Cloud Storage is a RESTful service for storing and accessing your data objects on Google’s infrastructure. Few important features: Multiple layers of redundancy. All data replicated to multiple data centers. Objects can be terabytes in size, with resumable uploads and downloads, and range read support. If you wish to start with Google cloud storage, a good starting point will be to click on the image to the left. In my session, I’ve covered:

  • Migrating Data to Cloud Storage
  • Object Composition
  • Durable Reduced Availability Storage Continue reading

Memcache Basics On Google App Engine

memcache on GAEThis week is packed with great content on “Google cloud platform”. I will summaries some of the talks we having in our office. The first talk I gave was on leveraging memcache when you developing with Google App Engine. Here is the summary:

What is Memcache?

Memcache is an in-memory key-value pairs data store. You can use the put(key, value) and get(key) in order to save and fetch data from it. key or value can be anything that is serializable. It’s important to remember that with GAE – Memcache is a shared service accessed via App Engine APIs. So it’s not a RAM base caching layer that you might have on a single server but a service that you will make a network call each time you write/read from it. Continue reading

Google Cloud Platform Update

Google cloud platform updateYesterday we had a very cool event at Google’s offices. There were many mobile and web developers that came to hear what is new with Google cloud technologies (among other thing). I’ve used this set of slides because I knew they will be useful to many more developers that miss the event. That is the reason, I’ve used ‘a lot’ of words on each slide.

The event was recorded and I will update this post with the video soon. Have a great 2014! Continue reading
