I am from non-technical background. Is it feasible to start an IT service company? What are all of the segments I need to take care of?

https://www.filepicker.io/ is the best thing that you can integrate with this app which suits your requirement. If you are the owner of the app, you can integrate it very quickly. If not, you can suggest the app owner to do it Feel free to call me if you need more clarification. I am consulting architect for few companies in US and India on mobile, web and windows/linux/mac apps.

Yes, you should use hashtags to solve the query. But, it also means finding the right hashtags to use. Here's some things to look for with hashtags and some other ideas for growing your following: 1. Find trending hashtags. If a hashtag is only used 100 times, it will be difficult to "get into the mix." Find popular and trending hashtags to add into. 2. Don't use one word hashtags that everyone else is using. Phrases as well as specific to your topic are better to get responses. Remember that what you use as hashtags appears in results and will get noticeability depending on your focused topic, meaning you need to have relevant information to your brand and images. 3. Engagement. Participate in others conversations and use hashtags. Even if you aren't following someone, engage with their pictures and use hashtags. This will drive more engagement to your profile then back to your Instagram account. 4. Use longer descriptions. Hashtags are great. They are even better when you write more as a caption for your picture. These also serve as a keyword base to help followers find you. 5. Brand. I suggest looking at some of the top influencers and looking at what they are doing. You will notice that their pictures are all the same color, tone and with similar content. Someone will follow you if you add value to their scroll. Make sure you stick out from the crowd. There's always more to do with Instagram. :) It's an incredibly powerful tool and it builds your recognition in ways that other social accounts can't. Be consistent with your posts and you will get the followers you want. Have more questions? I'm happy to help! Contact me if you would like more info.

I've had great experience as a user of Udemy and write my own courses but offer those privately for my clients. It's always better to build a course that answers a specific need. Think about the avatar for your business. You can't meet everyone's needs. Build a course with no more than 8 segments or modules with 4 - 8 learning segments within each module. You will allow the user to achieve rapid and measurable results by completing each section and ending each module with an assessment (quiz) that further validates learning the skill. Udemy is easy to use so you will have a broad audience looking for specific needs.

It stands for allowing someone to continue doing or use something that is normally no longer permitted (due to changing regulations, internal rules etc.)

Back in 2010 we went through exercise of first using a local data center and then using a CDN in a different country. Interestingly enough using a remote CDN had much smaller latency. After doing an in depth analysis this is what we discovered. There are two factors that influence your latency: throughput of the pipe and speed of the physical server. Let's start with throughput. Consider two scenarios. In the first one you're using CloudFront from Amazon (or any other big name CDN) which probably has direct connection (or near direct) to the continents fiberoptic pipe. The second scenario is if you build a data center in the country. In this case you will be removed from the main pipe by several hops through internet providers which in turn will narrow the throughput after every hop. Unless you are willing to pay very expensive bill for the access to continents, or at least contries main pipe the latency will be higher than from big name CDN's. The second aspect deals with the type of servers involved in servicing GET requests. You need to install top notch hardware with very speedy SSD hard drives and extremely fast networking cards. You can go as far as start optimizing bus speeds between the components. All that leads to increase in price per server. If you're using a CDN then you're much better off because all of that is taken care of for you and you constantly run on latest and greatest hardware that you don't need to upgrade. Count in the amount of time/money need to be spend to service a data center. From my experience the companies that do administration on demand are slow for near 100% uptime requirements so you will need to hire and staff to do monitoring and maintenance. Also never forget about redundancy that also needs to be provided as your server will fail and will go down. Security is also a concern. My conclusion from the the evaluation done in 2010, which is much stronger today, go with CDN unless you're a Fortune-500 company and need a dedicated special use data center. Current CDN's usially offer multiple data centers at different continents for your disposal that can further shrink your response time. Good luck! Denis.
