 So, welcome to week six, what do we have here? Two topics, one is about cloud computing. In actual practice, when you want to actually deploy a system, an application, you may want to put it on the cloud, not host it on a server in your premises. That's the modern trend at least. It has a large number of advantages and this set of three lectures by Dr. Balvinder Sodhi will tell you about what is cloud computing, how many different ways you can deploy your application in the cloud. He will also demonstrate how to do it on one particular cloud service provider called Amazon Web Services. Then finally we have one lecture on geographical information systems by Dr. Balaji. Now GIS are the pinnacle of application of these technologies. You can actually look at a map, let's say the map of a district or a state and see what is the soil distribution, what is the outbreak of a particular pest, how is it moving. So, these kinds of maps and can be used for monitoring, for planning and so on. So Dr. Balaji will tell you about what is the GIS and how to use them. And then finally we have two assignments. These are very interesting assignments. These are on the social networking that we have learned last week. So the first assignment is you have to create a blog of your own. Go to one of the blogger sites, free blogging services that have been talked of in the lecture on blogs and create your own blog. You can write on anything, any topic of your interest. For example, you can write on the course that you are doing the ICT Basics course. And then what you need to submit is the URL of the blog. The next assignment is even more interesting. Let's say you are a tomato farmer and then you go one day into your field and find there are problems. There are the leaves seems to have some spots, they are small and circular to angular and they are here and there. There is a picture here which talks about it. In some cases the plant is completely defoliated. There are no leaves and so on. Now you need to find out what is this disease and how do I deal with it. And you want to use the social networking platforms to figure out. You want to get advice from your friends and colleagues on the network. You are going to use Facebook or Twitter for this. So, create accounts if you don't have, post your problem on Facebook or tweet and then get your friends to answer and help and see what the experience is and how it works out. So, the submission for this is your conversation that you have had. The series of posts that have been posted and answered and so on. That's the kind of document you can create and submit. This will be very interesting. You will learn all about how interactions happen on Facebook. Have fun.
