Pros & Cons
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.
Slack
Pros
- The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
- Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
- Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
- Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
- Workflow Builder automates routine requests and approvals without code.
Cons
- There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
- Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
- The free plan keeps only 90 days of message history and allows 10 apps.
- Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
- Reviewers report that finding older messages through search can be difficult.
