Introduction
Intention of this blog is to help people who want to get hands on to HANA Development using Amazon web services (AWS). I have explained the step by step process as on date of publishing this blog to get connected to an HANA instance on AWS. Those who are referring to the blog, please keep in mind that cloud service charges I mentioned below will be fluctuating from time to time, so make sure the charges falls in your budget .
Setting up an Amazon (AWS) Account
- You will require an Amazon account for using Amazon web services(AWS), for that go to [ https://aws.amazon.com/ ]. If you already have an amazon account use that account else create a new account, you will have to furnish your credit card / Debit card details here. Your monthly invoice amount will be detected from this account. Make sure you enter valid details here.
- As part of validating your account details AWS will charge you a small amount ( 2 INR for me)
- There will be IVR verification of your mobile number.Once verified you will be prompted to select a support plan, as our usage is purely training you can go for Basic support plan which is free.
- Proceed to AWS Management Console
- Click on your Account name and from the drop-down select Security credentials
- In this screen expand the access keys and “Create new access key”. This information is important, because anyone who knows this information can access your training system which will incur you charges. Once you press this button, it will generate access key and will ask you to save it as text file, save this information securely as this information will be required by you whenever you wanted different services from AWS.
- You will get an Access key and secret key with the above action which will be used for configuring your solution
Set up Hana Instance in Cloud appliance Library
- Use your SAP Community Network credentials [ if you dont have a SCN user go to https://www.scn.sap.com/ and signup your self ] to logon to SAP Cloud Appliance Library[ https://cal.sap.com ]
- Go to Accounts tab
- On the right corner of the above you can see “Create account” Press this button
- Select the cloud provider as Amazon Webservices in the next screen and provide the Access key and Secret key what you got from AWS while registration here for setting up the account ( You can leave the cost assignment field ) and press finish
- Note down your SCN user id for future references ( P*****)
- Once you finish you can see your username configure in the accounts console on SAP cloud appliance library
- Now go to the solution tab and search for “SAP HANA developer edition”. Activate / Trynow the latest SPS available
- It will show as create Instance, where you have to press the create instance button
- Once you press create instance it will show you the following screen with pricing information, the highlighted amount is the charges applicable. Amazon will charges you additional for keeping you instance data on cloud as per their pricing [ As per my experience it was 0.48 USD + 1 USD which will cost you around USD 1.5 approximately 100 INR per hour. But this is dependent on how many objects you develop, I recommend you to store as less objects as possible to keep the charges on your training down
- In the next screen you will be able to see the access, in which you can see the ports HANA use for connecting to cloud server. So please make sure the ports are open otherwise you will find it difficult in connecting to HANA Instance
- Set your solution password, these will be used for your HANA studio login
- In the Schedule tab select Manually Suspend & Activate
- Once you finish, it will ask to save the private instance key. Save it securely where you can access it later also
- It will take 20 mins for your HANA system to get set up right and running
- Once the instance is ready it will show a green icon, the click on your Instance name
- Now you can see the server IP details as below
- Install HANA Studio on your PC [ Refer the link for HANA studio installation SAP Development Tools for Eclipse ]
- Open your HANA Studio and go to system tab, right click and click add system
- Press Next & Give the user name as SYSTEM & Password as the solution password you set earlier in cloud appliance library and press finish
- Once your instance is ready to get started, you can see the added server as green or yellow ( Some time due to error in initiating web services the instance show yellow, but there is nothing to worry, it won’t stop your from doing the modelling / creating views )
NB : You should always take care that once you are done with your development practicing, you must go to your CAL account and "SUSPEND" the instance else if you simply log off from hana studio, AWS will charge you for the time till you suspend the instance. There will be also a "TERMINATE" button against your instance, if you wish NOT TO store your objects you can use this which will delete the HANA instance, next time you have to set up a new one.
Also each time when you activate your instance the External IP will change. So you will have to go to your studio and change the IP of the added system. If you like you can opt for static IP while setting up your instance but there will be again charges involved for the static IP.
