One of my clients is based in Indonesia. The company had achieved dramatic success in the mobile field
Having built IT integration products for the business-to-business sector since 2006, a 70-strong developer team recently turned their attention to mobile apps developing a secure instant messaging service called EMASS (Encrypted Messaging and Secured Services).
Their objective was to create a platform that enables customers or employees to use messaging for secure transactions. They planned to market EMASS to banks and phone companies, so their customers could make payments and buy top-ups using a single log-on from their cell phones.
To launch EMASS as a service, my client needed a cost-effective way to host the EMASS backend systems for each mobile app. They also expected that customers would want to use EMASS from overseas, but this presented a dilemma.
“Deploying EMASS on overseas servers would have been prohibitively expensive...”
“Deploying EMASS on overseas servers would have been prohibitively expensive...”
Hosted EMASS servers in Indonesia, the client would also face speed and bandwidth issues.
They are after all a software-development company, not a service provider. They needed a partner (hence my role) to host EMASS for them, but their service had to be reliable, easy to work with and affordable. For financial institutions to trust them, it also had to be 100 percent secure.
The cloud solution
A cloud service that worked with EMASS was my brief and I was able to use a wide mix of technologies. These included Java and Linux for core server messaging, and C# for satellite modules attached to the core servers. On the client side, we used C#/XAML for the Windows Phone app, and C# for the iOS and Android apps, with the latest version of Xamarin on Visual Studio.
I evaluated several options, including a managed, on-premise deployment with data network firm, an infrastructure as a service (IaaS) solution from local cloud provider, Biznet Network; and two cloud platform services on Windows Azure.
The on-premise solution required a large capital investment, because the client would have to purchase and install servers. The IaaS option would also be costly, because staff would have to manage the operating system and scale the apps.
The solution
We had to deliver the easiest cloud platform to work with, Security and patching be already taken care of, so it is less labour-intensive. Although we used Linux and Java to create our payments messaging system, Azure can easily handle them because of its open architecture.
I also advised about deploying EMASS, which included migrating the backend database to MSSQL. With over 15 cloud apps running on 30 virtual machines on Windows Azure, the client began offering EMASS to banks. The service became an instant success after it was published to the cloud and tested.
With Windows Azure, I was able to provide the client with support of all open source technologies used in EMASS. Azure has proved secure and reliable, so financial institutions trust my client to create new services for their own customers.
The bottom line
Azure saved the client these capital and operational expenses, in return for a predictable and transparent monthly charge.
Minimal IT support required
The Windows Azure service also reduces costs, because it needs minimal IT support. With Azure, you can forget about managing a rack of servers, the network, security and patching.

Moreover, we can empower clients to easily manage scalability from their own PC. If they had hosted it themselves it would need at least five system administrators; with Windows Azure they only needed one.
Fast deployment times for mobile appsMy solution used the Mobile Push Service feature within Windows Azure Mobile Services to build the backend services for each app.
With Azure Mobile Services, we can develop our mobile apps very fast. And it’s very easy to deploy on Windows Azure: the interface is very good, and the result is perfect.
