RPO
What is Recovery Point Objective?
A collection of related resources
What is a compartment?
Enable large scale deployment of VM's from a single gold image with automatic configuration
Storage for compute instances. That is either for Boot or data disks.
The service lets you store data independently of the lifespan of compute instances.
Data is encrypted at rest and in transit
What is Block Volume service?
All data stored in a 'bucket' and is managed as objects. Objects are stored in a single flat structure. Commonly used for Content repository, log data or archival backups.
- data is encrypted at rest, but not in transit
What is object storage?
RTO
What is Recovery Time Objective
A hypervisor to virtualize underlying bare metal server into small VM's (multi-tenant VMs)
Container
- Basic (for throughput intensive with large sequential I/O)
- Balanced (for most workloads including random I/O - boot disks)
- Higher Performance (most demanding I/O performance such as large DB)
What is Block Volume tiers?
Virtual Cloud Network
Software defined private network set up in OCI
What is VCN?
Availability Domain
What is One or more fault-tolerant, isolated data centers within a region.
Run your VM instances on dedicated bare-metal servers (single-tenant VMs)
Dedicated VM Hosts
Oracle Kubernetes Engine
What is the fully managed, scalable and highly available service used to deploy containerized applications in OCI?
Temporary storage attached to compute instance. Used for applications that require high performance local storage such as transactional DB. It will survive a reboot.
What is Local NVME?
provides path for network traffic between your VCN and the internet
What is internet gateway?
Fault Domains
What is Grouping of hardware and infrastructure within an Availability Domain
Change the shape of an instance (add or remove resources)
What is vertical scaling (scaling up or down)?
Small, powerful blocks of code that generally do a simple thing and are stored as docker images.
Functions
Hierarchical collection of documents organized into named directories (local file systems)
data is encrypted at rest and in transit
What is File Storage?
allows outbound connection to the internet but blocks inbound connections initiated from the internet (used for patches and updates)
What is NAT Gateway?
Bare Metal
What is Direct Hardware Access
Add or remove instances
Data stored on a device in fixed sizes and access by the OS. No high level metadata is stored and is commonly deployed in SAN
What is Block Storage?
FSS
What is File Storage Service?
Virtual router that provides a path for private traffic between the VCN and destinations other than the internet - (on prem)
What is DRG (dynamic routing gateway)?
