To serve web traffic for a popular product, your cloud engineer has provisioned four BM.Standard2.52 instances, evenly spread across two availability domains in the us-ashburn-1 region; LoadBalancer is used to deliver the traffic across instances.After several months, the product grows even more popular and you need additional compute capacity. As a result, an engineer provisioned two additional VM.Standard2.8 instances.You register the two VM.Standard2.8 instances with your Load Balancer Backend set and quickly find that the VM.Standard2.8 instances are now running at 100% of CPU utilization but the BM.Standard2.52 instances have significant CPU capacity that's unused.Which option is the most cost effective and uses instances capacity most effectively?
You are a solutions architect for a global health care company, which has numerous data centers around the globe. Due to the increasing volume of data that your company stores, you are tasked with setting up a durable, cost-effective solution to archive data from existing on-premises tape-based backup infrastructure to Oracle Cloud Infrastructure (OCI).Which is the most effective mechanism to implement this requirement?
A company runs a public-facing application that uses a Java-based web service via a RESTful API in their on-premises data center. Use of the API is expected to double with a new product launch. The business wants to migrate their application to Oracle Cloud Infrastructure (OCI) to meet the scale and reliability requirements.In order to achieve this, they will divert only 40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the remaining 60% traffic through their on-premises infrastructure. Once the migration is complete and application works fine, they will divert all traffic to OCI.How can these requirements be met with the LEAST amount of effort?
You are developing a Serverless function for your company's IoT project. This function should access Oracle Cloud Infrastructure (OCI) Object Storage to store some files. You choose Oracle Functions to deploy this function on OCI. However, your security team doesn't allow you to carry any API Token or RSA Key to authenticate the function against the OCI API to access the Object Storage.What should you do to get this function to access OCI Object Storage without carrying any static authentication files?
Your company developed a function that needs to access the Oracle Database to inject some data to it at runtime. You are tasked to move this function to the Oracle Cloud Infrastructure (OCI) and use Oracle Functions and access Oracle Autonomous Database. You created a Dockerfile below to run this function, however, you are getting this error "cx_Oracle.DatabaseError: ORA-12560: TNS:protocol adapter error".What should you do to make sure that Oracle Functions can run this Dockerfile properly?
A consulting company that employs Oracle Cloud Infrastructure (OCI) architects has successfully completed resource migration from Microsoft Azure to OCI, and no longer requires the OCI FastConnect circuit to Azure. The project manager has asked you to delete all resources involved in this inter-cloud connectivity. From the Azure side, you delete the Resource Group. After a while, you notice that all Azure resources have been deleted, except for the Azure ExpressRoute circuit.What could be a potential reason for this issue?
