@Poonam K Also I searched for inhouse app distribution ,I found that we need to create accont for apple developer enterprise program.
Can any one tell me is there another to deply inhouse iPAD app ? or can we do over the air deployment of iPAD app ?
Over the air deployment has been available since iOS 4 (as I recall the version it got enabled). But it is not as simple as doing a HTTP link to the *.ipa; there are a few hoops you have to jump through to pull it off.
If you need under 1000 installs and all devices are at least iOS 9 (or so?), then you may find Testflight is the easiest way to go. You only need the email address of each person to authorize. It not only helps with the install or updates, but you can actually disable specific people too (perhaps due to company attrition).
But if you want to do over the air installs -- what I have done since iOS 4 -- then by far the easiest method is to also have an Enterprise license. With it, you obtain a provisioning profile that can be installed on unlimited devices without having to collect the device UDID to add like ad-hoc profiles. But once installed, you can't disable specific devices -- the profile is good for up to a year.
Your choices include:
- Free profile: these are good for only a week, so a poor choice except in limited testing scenarios or during development
- Regular developer proflie ($99/year): You still need to pre-authorize each device UDID, and I think is limited to 100 devices
- Enterprise profile ($399/year, I think): Unlimited installs, and no need to pre-authorize each device UDID
The Enterprise license does have several restrictions as to what is allowed. And applications for it are not automatically approved -- at least the last time I was involved with one it took a few months to obtain approval. Maybe it is different now.
Anyway, until recently you could install over the air via HTTP but now HTTPS is required for the actual file (although a web page with a link to it can be HTTP). So what some people have done is use Dropbox to host the necessary files, then use a URL shortener to point to the Dropbox location.
Two of the many hits in a web search just now:

Distributing an IPA over the air with dropbox — iOS 10 in five minutes
Be aware too the app must have the distribution provisioning profile included (ad hoc or enterprise) and be in an *.ipa format. There is another thread discussing doing that with Xojo here
