Problem with Alibaba instance

I cretae a ubuntu instance and installed apache2 , and create a sample page in var/www/html/inde.html but i am unable to access the file using the browser(used the ip provided by the instance). Does this need to have some other permissions or wat???..wasted a lot of time

Read about security groups and add some security rule which allows your networks ip to access the instance which you have created.

can u share any url resource regarding that, i am new to this…

First, please ensure you are using public IP rather than the private IP address. Then. As @tanmaydatta mentioned, please check the security group to see if the TCP port 80 is allowed.

For detail step about how to add a security group rule, please check the document below:
