What are the differences between Jira / Confluence Cloud (Free, Standard, Premium and Enterprise)

Atlassian Access gives an organization centralized control, visibility, and increased security across all Atlassian cloud products. Access helps admins
– increase security 
– automate user lifecycle management with SAML SSO
– user provisioning (SCIM)
– audit logs
– and more

For the purpose of illustration, we tabulated the monthly subscription cost of Jira Software Cloud.

– Premium plan starts at 2 times of the Standard plan
– As you add more users, the average price per user will decrease
– For annual subscription, there will be 2 months free

Check this table for the differences between monthly and annual payment

You can use the Cloud Pricing Calculator to estimate your bill.

It really depends on a number of factors such as
– Cost – It is very cheap to host on Cloud if you have a small team
– Control – to view the log files, dictate when to perform upgrades, site url, etc
– Customisation – one of the major strengths of Atlassian products is that they are extensible
– Expertise – whether there are people to manage and support the solution
– Features – some of the apps on Marketplace are not available for Cloud. So do check it out first
– Integration with other systems – linkage with corporate LDAP, Single Sign On (SSO) solutions
– Performance – it is definitely faster if the server is within your network

It is still possible to host a Server/Data Center on Cloud infrastructure like 
– Amazon AWS
– Microsoft Azure
– or your own private Cloud

It depends.
