Boosting Oracle Cloud Infrastructure Performance: Unleashing the Benefits of Ansible with OCI Block Storage

MarkBurgessMark Burgess  |  


In the dynamic landscape of cloud computing, optimising performance and automating infrastructure management are crucial elements for success. Oracle Cloud Infrastructure (OCI) offers a powerful solution with its Block Storage Dynamic Performance feature, allowing users to adapt to varying performance requirements. This blog post explores the advantages of integrating Ansible, a leading automation tool, with OCI Block Storage Dynamic Performance to enhance agility and efficiency in managing cloud-based applications.

Understanding OCI Block Storage Dynamic Performance

What is Dynamic Performance?

OCI Block Storage Dynamic Performance provides users with the flexibility to adjust the performance characteristics of their block volumes dynamically. It enables seamless scaling of I/O performance based on application needs, allowing organizations to optimize both cost and performance.

Why is this feature so powerful?

OCI Block Volume performance can be modified online and typically completes within minutes (dependent on volume size). This allows IO performance to be increased or decreased in near real-time depending on workloads.

Harnessing Ansible for OCI Block Storage Dynamic Performance

Why Ansible?

  1. Declarative Configuration: Ansible’s declarative language enables users to define the desired state of their infrastructure, including block storage performance settings. This simplifies configuration management and ensures consistency across the environment.
  2. Automation Playbooks: Ansible playbooks, written in YAML, allow for the automation of complex tasks. Creating playbooks for OCI Block Storage Dynamic Performance enables users to scale performance, modify configurations, and adapt to changing requirements seamlessly.

Benefits of Using Ansible with OCI Block Storage Dynamic Performance

1. Agility in Performance Scaling:

Ansible allows organizations to dynamically adjust block storage performance through playbooks, responding promptly to changing workloads. This agility ensures that applications receive the necessary I/O performance without manual intervention.

2. Cost Optimisation:

OCI Block Storage Dynamic Performance, combined with Ansible automation, offers a cost-effective solution. Users can scale up performance during peak workloads and scale it down during off-peak hours, optimizing costs without sacrificing application performance.

3. Consistency Across Environments:

Ansible playbooks provide a consistent and repeatable method for configuring block storage performance. This consistency ensures that performance settings are applied uniformly across different environments, reducing the risk of configuration drift.

4. Efficient Resource Management:

With Ansible, IT teams can efficiently manage block storage resources, allocating performance where it is needed most. This ensures that critical applications receive the necessary performance boost while avoiding unnecessary costs for less demanding workloads.

5. Automation of Complex Tasks:

OCI Block Storage Dynamic Performance may involve several configuration changes. Ansible simplifies this complexity by automating tasks such as volume resizing, changing performance tiers, and adjusting IOPS and throughput with ease.

Implementing Ansible Playbooks for OCI Block Storage Dynamic Performance

1. Install Ansible Modules:

Ensure that the necessary OCI Ansible modules are installed on your control node:

ansible-galaxy collection install oracle.oci

2. Create Dynamic Performance Playbooks:

Develop Ansible playbooks to dynamically configure block storage performance settings based on your application requirements.

The following example playbook obtains the attached block volumes for an instance and sets the VPU per volume based on the relevant tag values:

- name: Get OCI Instance
compartment_id: "{{ cmp_id }}"
config_file_location: /home/ansible/.oci/config_ansibleoci
display_name: "{{ hostname }}"
register: oci_instances
- name: Set instance id
instance_id: "{{ item.id }}"
loop: "{{ oci_instances.instances }}"
- name: Set instance tier type
abc_tier: "{{ item.defined_tags.ResourceLabelsABC.ABCTier }}"
loop: "{{ oci_instances.instances }}"
- name: Get volume attachments oci
compartment_id: "{{ cmp_id }}"
config_file_location: /home/ansible/.oci/config_ansibleoci
instance_id: "{{ instance_id }}"
register: vol_attachments
- name: List Block Volumes
compartment_id: "{{ cmp_id }}"
config_file_location: /home/ansible/.oci/config_ansibleoci
volume_id: "{{ item.volume_id }}"
register: vol_details
loop: "{{ vol_attachments.volume_attachments }}"
- name: Set BV Performance Level Low - DB Tier
compartment_id: "{{ cmp_id }}"
config_file_location: /home/ansible/.oci/config_ansibleoci
state: present
wait_timeout: 2400
volume_id: "{{ item.volumes.0.id }}"
vpus_per_gb: "{{ item.volumes.0.defined_tags.StoragePerformanceTierLowABC.DatabaseTier }}"
when: (( item.volumes.0.defined_tags.ResourceLabelsABC.ABCEnvironmentName == "ORA1" or item.volumes.0.defined_tags.ResourceLabelsABC.ABCEnvironmentName == "ORA2" ) and ( item.volumes.0.defined_tags.ResourceLabelsABC.ABCTier == "Database" ) and ( item.volumes.0.defined_tags | length > 0 ) and ( {{ tier_perf == "Low" }}))
loop: "{{ vol_details.results }}"


Integrating Ansible with OCI Block Storage Dynamic Performance empowers organisations to achieve a perfect balance between agility, performance, and cost-effectiveness. By automating the configuration of block storage performance, IT teams can respond promptly to changing workloads, optimise costs, and ensure consistent performance across their cloud environments. Embrace the power of automation with Ansible, and unleash the full potential of OCI Block Storage Dynamic Performance in your Oracle Cloud Infrastructure.

What are the specific prerequisites and technical requirements for integrating Ansible with OCI Block Storage?

Integrating Ansible with OCI Block Storage typically requires a working knowledge of both Ansible and OCI, including configured API access and familiarity with OCI’s block storage offerings.

Can Ansible be used to automate other aspects of OCI beyond block storage performance adjustments?

Ansible can automate a wide range of tasks in OCI beyond block storage, such as provisioning and managing compute instances, networks, and other cloud resources, thanks to its extensible nature and the availability of OCI modules.

How does the use of Ansible with OCI compare to other automation tools in terms of efficiency and ease of use?

Ansible’s efficiency and ease of use compared to other automation tools often depend on the specific use case and the user’s familiarity with the tool. Ansible is known for its simplicity and declarative language, making it accessible for automating tasks without extensive scripting.
