This Week I Learned -
* What is the RPO and RTO with Geo-redundant storage (GRS)?
In GRS and RA-GRS, the storage service asynchronously geo-replicates the data from the primary to the secondary location. In the event that the primary region becomes unavailable, you can perform an account failover (preview) to the secondary region. When you initiate a failover, recent changes that haven't yet been geo-replicated may be lost. The number of minutes of potential data that's lost is known as the RPO. The RPO indicates the point in time to which data can be recovered. Azure Storage typically has an RPO of less than 15 minutes, although there's currently no SLA on how long geo-replication takes. The RTO is a measure of how long it takes to perform the failover and get the storage account back online.
* To move Azure resources to either another Azure subscription or another resource group under the same subscription. You can use the Azure portal, Azure PowerShell (Move-AzResource or Move-AzureRmResource), Azure CLI (az resource move), or the REST API to move resources.
* Difference between RBAC & Azure Resource Lock
Unlike role-based access control, you use management locks to apply a restriction across all users and roles. Of the built-in roles, only Owner and User Access Administrator are granted permission to create or delete management locks.
* Difference between RBAC & Azure Policy
RBAC focuses on user actions at different scopes. You might be added to the contributor role for a resource group, allowing you to make changes to that resource group. Azure Policy focuses on resource properties during deployment and for already existing resources. Azure Policy controls properties such as the types or locations of resources. Unlike RBAC, Azure Policy is a default allow and explicit deny system.
* Katacoda.com has many useful browser based Labs & courses
* EC2Instances.info makes it easy to compare pricing & specs of AWS EC2 instances
* With GRS, the replica isn't available for read or write access unless Microsoft initiates a failover to the secondary region. In the case of a failover, you'll have read and write access to that data after the failover has completed.
* Pegasystems has 1600 employees across Hyderabad & Bengaluru, a third of global workforce
* Amazon and Apple don't offer employees free food as a workplace benefit.
* Amazon currently has 17 localized storefronts differentiated by top-level domain and country code
* Singapore has a population of 5.6 million and has a unique universal healthcare system widely regarded as one of the best in the world.
* Many infections cause fever, headaches, and fatigue. Many mental health disorders cause sadness, anxiety, and sleep problems. A differential diagnosis looks at the possible disorders that could be causing your symptoms. It often involves several tests.
* Dr Hemant Morparia who draws for The Economic Times also works as a radiologist
* Most of us want just three specific things from our jobs, namely:
A sense of competence and mastery
A sense of community or affiliation
A sense of meaning and purpose
