# Cloud Provider Instance Types: A Guide for MediaWiki Administrators

This article provides a comprehensive overview of cloud provider instance types commonly used for hosting a MediaWiki 1.40 installation. Choosing the correct instance type is critical for performance, scalability, and cost efficiency. We will cover key considerations and popular instance families from major cloud providers. This guide is geared towards newcomers to server administration and assumes a basic understanding of virtual machines and cloud computing concepts.  See also [[Server Requirements]] for baseline needs.

== Understanding Instance Types ==

Cloud providers offer a vast array of instance types, each optimized for different workloads. These types differ in vCPU (virtual CPU) count, memory (RAM), storage options (SSD, HDD), network performance, and cost. Selecting the right instance involves balancing these factors based on your MediaWiki's specific needs. Factors to consider include:

*   '''Traffic Volume:''' Higher traffic necessitates more CPU and memory.
*   '''Database Size:''' Large databases require more storage and potentially faster storage (SSD).  See [[Database Configuration]] for details.
*   '''Extensions:''' Complex extensions (e.g., [[Semantic MediaWiki]], [[VisualEditor]]) increase resource requirements.
*   '''User Count:''' A larger user base demands more resources for concurrent sessions.
*   '''Budget:''' Cost is a significant factor; optimize for performance within your budget.  Consider [[Cost Optimization]] techniques.

== Amazon Web Services (AWS) Instance Types ==

AWS offers a wide variety of instance families. Here are a few commonly used for MediaWiki:

{| class="wikitable"
! Instance Family
! Description
! vCPUs
! Memory (GiB)
! Storage
! Suitable For
|-
| t3.medium
| General purpose, burstable performance. Good for low to moderate traffic.
| 2
| 4
| EBS only
| Small to medium-sized wikis.
|-
| m5.large
| Balanced compute, memory, and networking. Reliable for most workloads.
| 2
| 8
| EBS only
| Medium-sized wikis with moderate traffic.
|-
| r5.large
| Memory-optimized for demanding applications.
| 2
| 16
| EBS only
| Large wikis with complex extensions or high caching needs. See [[Caching Configuration]].
|-
| c5.large
| Compute-optimized for CPU-intensive tasks.
| 2
| 8
| EBS only
| Wikis performing a lot of complex calculations or utilizing advanced features.
|}

For more detailed information, refer to the [[AWS Instance Types]] documentation.  Always monitor CPU utilization and memory usage using [[Monitoring Tools]] to determine if resizing is needed.

== Google Cloud Platform (GCP) Instance Types ==

GCP also provides a variety of instance types. Here's a selection relevant to MediaWiki deployments:

{| class="wikitable"
! Machine Type
! vCPUs
! Memory (GiB)
! Disk Options
! Suitable For
|-
| e2-medium
| 2
| 4
| HDD, SSD
| Small to medium-sized wikis. Cost-effective.
|-
| n1-standard-2
| 2
| 7.6
| HDD, SSD
| Medium-sized wikis with moderate traffic.
|-
| n1-highmem-4
| 4
| 15.3
| HDD, SSD
| Large wikis with complex extensions or high caching needs.
|-
| c2-standard-4
| 4
| 15.3
| HDD, SSD
| CPU intensive tasks, like large import jobs.
|}

See the [[GCP Machine Types]] documentation for a complete list and specifications.  Consider using [[Managed Instance Groups]] for scalability.

== Microsoft Azure Instance Types ==

Azure offers virtual machines (VMs) that can be used to host MediaWiki. Here's a simplified table with common options:

{| class="wikitable"
! VM Size
! vCPUs
! Memory (GiB)
! Storage
! Suitable For
|-
| B2ms
| 2
| 8
| SSD
| Small to medium-sized wikis.
|-
| D2s_v3
| 2
| 16
| SSD
| Medium-sized wikis with moderate traffic and database size.
|-
| E4s_v3
| 4
| 32
| SSD
| Large wikis with high traffic and complex extensions.
|-
| F2s_v2
| 2
| 8
| HDD
| Cost-effective option for wikis with less frequent access.
|}

Refer to the [[Azure Virtual Machine Sizes]] documentation for comprehensive details.  Azure provides [[Autoscaling]] features for dynamic resource allocation.

== Storage Considerations ==

Regardless of the cloud provider, the choice of storage is critical. 

*   '''SSD (Solid State Drive):''' Preferred for databases and frequently accessed files (images, JavaScript, CSS). Offers significantly faster read/write speeds.  See [[Database Performance Tuning]].
*   '''HDD (Hard Disk Drive):''' Suitable for archiving infrequently accessed data.  More cost-effective for large storage volumes but slower performance.

Consider using a separate EBS volume (AWS), Persistent Disk (GCP), or Managed Disk (Azure) for your MediaWiki database to improve performance and scalability.

== Conclusion ==

Selecting the appropriate cloud provider instance type is a crucial step in setting up a successful MediaWiki deployment. Carefully assess your wiki's requirements, budget, and growth projections. Regularly monitor resource utilization and adjust your instance size as needed to ensure optimal performance and cost efficiency. Don't forget to explore [[Load Balancing]] for high availability and scalability. Finally, remember to consult the official documentation for each cloud provider for the most up-to-date information.
