Amazon Web Services (AWS)

Pros

• The service catalogue is unusually broad, with over 200 services across 38 regions, so most infrastructure needs can be met on one platform.
• EC2 has a 99.99% region-level SLA with credits of up to 100%, and instances unavailable for more than six minutes in an hour are not billed for that hour.
• The free plan gives up to $200 in credits, and more than 30 always-free services let new teams experiment at low cost.
• Support scales from a $29 minimum up to dedicated Enterprise and Unified Operations tiers for mission-critical workloads.
• G2 rates it 4.4 across more than 17,000 reviews, and reviewers praise its scalability and global reach.

Cons

• Reviewers widely cite a steep learning curve across the console and services.
• Usage pricing is complex and can produce unexpected bills unless spend is monitored closely.
• Paid support is billed as a percentage of total AWS spend, so support costs rise with usage.
• A July 2025 billing console bug showed customers estimated charges in the billions, which hurt trust in its cost tooling.

Glean

Pros

• Glean lists more than 275 connected apps, so employees can search Slack, Drive, Jira, Salesforce and other tools from one place.
• Search results follow each source system's access controls, which lowers the risk of exposing data to the wrong people.
• AI answers include citations that link back to the source documents, so users can check them.
• Developers get Client and Indexing APIs, a Web SDK, agent toolkits and an MCP server for building on Glean.
• Its compliance certifications include SOC 2 Type II, ISO 27001, ISO 42001 and HIPAA.

Cons

• Glean publishes no prices; third-party reports put seats at about 50 dollars or more per user per month with minimums of roughly 100 seats.
• There is no free trial, and some reports describe proofs of concept as paid.
• Setup, permission configuration and relevance tuning take significant work from IT teams.
• Reviewers report renewal increases of about 3 to 12 percent a year and possible extra fees for premium support.
• Some users report answers that do not fully match the source data, and say the ranking is hard to customize.
