It really depends on what type of industrial application you are interested in since industrial is a very fragmented market with multiple verticals. Most big SI companies like TCS, Accenture, infosys, Wipro, have IoT practices these days and do both application and hardware development.

Hello , I would suggest to be more specific as Application Development in IoT is highly specific for every industry and even use cases in the same industry. So the basic questions you need to ask first - who will be using the Application? what are the devices you are making IoT ? What is the data volume per day per session per month ? What is the uplink/downlink speed per device? How many devices should be rolled out? Is that data being collected in the Cloud or elsewhere? How secure the Application/Data should be ? What are the geographies - Global, USA, EMEA, APAC etc? Based on the profile you can find the right Architecture and then you can get a reasonable Application development supplier. I can discuss on the phone in more detail.

Hi, as this question was asked 4 years ago, with nary an answer, I assume you've found your own way:)

What did you discover?

I'd love to hear about where you ended up - the space has changed a lot over the last 4 years and, in that time, I have gathered together a huge amount of information on the various network options, suppliers (hardware and software), systems, solution providers and more.

We are launching our own IoT system integration service her in Malaysia and designing our own products to suit the market needs as well.

Love to chat:)
