Kaa: An Easy-to-Use Plat­form for Build­ing IoT So­lu­tions

Kaa is a multi-pur­pose mid­dle­ware plat­form for the In­ter­net of Things that al­lows build­ing com­plete end-to-end IoT so­lu­tions, con­nected ap­pli­ca­tions, and smart prod­ucts.

Kaa is a 100 per cent open source mid­dle­ware plat­form for build­ing end-to-end IoT so­lu­tions, con­nected ap­pli­ca­tions and prod­ucts. The Kaa IoT plat­form is li­censed un­der Apache 2.0. Kaa takes care of all the back­end heavy lift­ing and al­lows ven­dors to con­cen­trate on max­imis­ing their prod­uct’s unique value. It is hor­i­zon­tally scal­able, fault­tol­er­ant, and pro­vides a broad set of fea­tures. Kaa was cre­ated for IoT com­pa­nies and in­di­vid­u­als in­ter­ested in re­tain­ing own­er­ship of the en­tire tech­no­log­i­cal stack that they cre­ate.

An overview of Kaa

Kaa is a multi-pur­pose mid­dle­ware plat­form for the IoT that al­lows you to cre­ate com­plete and smart ap­pli­ca­tions. The Kaa plat­form pro­vides an open, fea­ture-rich tool­kit for the IoT prod­uct de­vel­op­ment process and thus dra­mat­i­cally re­duces the associated costs, risks and time-to mar­ket. It of­fers a set of out-of-the-box en­ter­prise-grade IoT tools that can be easily plugged in and im­ple­mented in a large ma­jor­ity of the IoT use cases.

There are nu­mer­ous architectural specifics that make IoT de­vel­op­ment with Kaa fast and easy. First, Kaa is hard­wareag­nos­tic and thus com­pat­i­ble with vir­tu­ally any type of linked de­vice, sen­sor and gate­way. It also pro­vides a clear con­struc­tion of IoT fea­tures and ex­ten­sions for dif­fer­ent types of IoT ap­pli­ca­tions. These can be used al­most as plug-and-play mod­ules with min­i­mal ad­di­tion of code on the de­vel­oper’s part. Kaa in­tro­duces stan­dard­ised meth­ods that en­able in­te­gra­tion and in­ter­op­er­a­tion across con­nected prod­ucts. And it is de­signed to be ro­bust, flex­i­ble, and easy-to-use and de­ploy.

Kaa’s fea­tures

Some fea­tures of Kaa that en­able key IoT capabilities are listed be­low:

1. Analy­ses user be­hav­iour and de­liv­ers tar­geted no­ti­fi­ca­tions.

2. Man­ages an un­lim­ited num­ber of con­nected de­vices.

3. Per­forms real-time de­vice mon­i­tor­ing.

4. Per­forms re­mote de­vice pro­vi­sion­ing and con­fig­u­ra­tion.

5. Cre­ates cloud ser­vices for smart prod­ucts.

6. Sets up cross-de­vice in­ter­op­er­abil­ity.

7. Dis­trib­utes over-the-air firmware up­dates.

8. Col­lects and analy­ses sen­sor data.

9. Per­forms A/B ser­vice test­ing.

How it works

Kaa en­ables data man­age­ment for con­nected ob­jects and the back­end in­fras­truc­ture by pro­vid­ing the server and end­point SDK components. The SDKs get em­bed­ded into your con­nected de­vice and im­ple­ment real-time bi-di­rec­tional data ex­change with the server. Kaa SDKs are ca­pa­ble of be­ing in­te­grated with vir­tu­ally any type of con­nected de­vice or mi­crochip.

The Kaa server pro­vides all the back­end func­tion­al­ity needed to op­er­ate even large scale and mis­sion-crit­i­cal IoT so­lu­tions. It han­dles all the

com­mu­ni­ca­tion across con­nected ob­jects, in­clud­ing data con­sis­tency and se­cu­rity, de­vice in­ter­op­er­abil­ity and fail­ure-proof connectivity.

The Kaa server fea­tures well-es­tab­lished in­ter­faces for in­te­gra­tion with data man­age­ment and an­a­lyt­ics sys­tems, as well as with prod­uct-spe­cific ser­vices. It acts as a foun­da­tion for the back­end sys­tem that you are free to ex­pand and cus­tomise to meet the spe­cific re­quire­ments of your prod­uct.

Why use Kaa?

The fol­low­ing fea­tures make Kaa dif­fer­ent from other mid­dle­ware plat­forms used to build IoT so­lu­tions:

1. 100 per cent open source and free.

2. Re­duces the de­vel­op­ment time from months to weeks.

3. Is rapidly evolv­ing, with new fea­tures be­ing added for free.

4. Pre-in­te­grated with data man­age­ment sys­tems.

5. No sin­gle point of fail­ure.

6. Easily tailored for any busi­ness ap­pli­ca­tion.

7. Min­imises the costs and risks of ap­pli­ca­tion de­vel­op­ment.

8. Straight­for­ward hard­ware in­te­gra­tion pro­ce­dure.

9. Han­dles mil­lions of de­vices and scales elas­ti­cally.

10. Sig­nif­i­cantly re­duces de­vel­op­ment time by pro­vid­ing an ad­vanced, out-of-the-box IoT fea­tures set.
