Keycloak as a Service for Enterprises | Cloud IAM Made Easy

Keycloak as a Service for Enterprises | Cloud IAM Made Easy

"Keycloak as a Service" refers to Managed Keycloak, where third-party providers host, maintain, and scale the open-source Keycloak identity and access management (IAM) platform for you.

This removes the operational burden of managing servers, databases, and security patches while retaining the platform's flexible features like Single Sign-On (SSO) and Social Login.

Popular Managed Keycloak Providers (2026)

• Cloud-IAM: A major specialist providing fully managed, dedicated Keycloak clusters with vertical/horizontal scaling and 24/7 support.
• Phase Two: Offers hosted Keycloak with enhanced enterprise extensions (like Organizations) and support for custom themes and extensions via CI/CD pipelines.
• Clever Cloud: Provides Keycloak as a plug-and-play add-on with dedicated resources (Java, PostgreSQL, and file system).
• Elestio: Focuses on "No DevOps" deployments on various cloud providers with automated backups and live monitoring.
• AWS Marketplace (Solodev): Offers a "Keycloak Serverless" managed solution specifically optimized for the AWS ecosystem.

Key Benefits of Managed Keycloak

• Reduced Overhead: Providers handle software updates, OS patching, and database maintenance.
• High Availability: Most services offer an SLA (e.g., 99.95%) with multi-zone or multi-region redundancy to prevent downtime.
• No "Per-User" Pricing: Unlike competitors (Okta or Auth0), many Keycloak hosts charge based on infrastructure resources rather than the number of active users, which can be significantly more cost-effective at scale.
• Compliance Ready: Providers often offer certified hosting (ISO 27001, SOC 2, GDPR) in specific regions like Germany or the US.

Core Features Maintained

Even in a managed environment, you typically retain full control over:

• Identity Federation: Connecting to LDAP, Active Directory, or other OIDC/SAML providers.
• Customization: Ability to upload custom themes and JAR-based extensions.
• Security: Standard protocols (OAuth 2.0, OpenID Connect, SAML 2.0) and Multi-Factor Authentication (MFA/Passkeys).

Why IAM Matters in the USA IT Sector?

The USA IAM market is booming, valued at $7.9 billion in 2024 and projected to hit $33.7 billion by 2032 (15.3% CAGR). Why? Cyberattacks are skyrocketing, 68% of USA breaches in 2024 involved stolen credentials. Whether you’re in tech, finance, or healthcare, a robust IAM solution like Keycloak ensures secure access, boosts user retention, and saves costs. For a Texas e-commerce client, we implemented Keycloak’s social login, increasing sign-ups by 15% in three months.

IAM isn’t just security, it’s a competitive edge.

Keycloak vs. Competitors: How It Stacks Up in the USA

The USA IAM market is crowded, with Keycloak holding a 1.83% share (1,252 customers) against giants like Azure AD and Okta.

  • Pros: Seamless Microsoft integration (Office 365, Azure), robust MFA, HIPAA-compliant.
  • Cons: $6-$9/user/month, less flexible for non-Microsoft stacks.
  • Best for: Enterprises tied to Microsoft ecosystems.
• Okta (~10%, 12,195 USA customers):
  • Pros: Cloud-native, 7,000+ app integrations, user-friendly SSO.
  • Cons: $15+/user/month, limited self-hosting.
  • Best for: SaaS startups needing quick setup.
• Ping Identity (~5%):
  • Pros: Biometric support, hybrid deployments, strong in finance.
  • Cons: Complex setup, costly for small businesses.
  • Best for: Large enterprises with legacy systems.
• Auth0 (~4%):
  • Pros: Developer-friendly, social logins, owned by Okta.
  • Cons: Limited self-hosting, premium pricing.
  • Best for: Developer-heavy startups.
• AWS Cognito (~3%):
  • Pros: Serverless, AWS-integrated, pay-as-you-go.
  • Cons: Cloud-only, limited customization.
  • Best for: AWS-centric companies.
• Others: FusionAuth, Ory, Supertokens (<1%), IBM Security Verify, CyberArk, SailPoint, OneLogin, Centrify (Delinea), ForgeRock, RSA SecurID, Oracle Identity Manager, SecureAuth.
  • Niche Strengths: CyberArk excels in privileged access, SailPoint in governance, RSA in high-security sectors.
  • Drawbacks: Often costly or specialized, lacking Keycloak’s flexibility.

Why Keycloak? It’s free, self-hosted, and supports hybrid deployments, saving 30-50% over Okta or Azure AD. Its 10,000+ GitHub stars prove its community strength.

Why Keycloak asa Service Wins for USA Businesses

Keycloak is a no-brainer for cost-conscious USA companies.

Here’s why:

• Zero Licensing Costs: Unlike Okta’s $15+/user/month, Keycloak’s Apache 2.0 license means you only pay for hosting ($100-500/month on AWS).
• Hybrid Flexibility: Supports cloud and on-premises, unlike Cognito’s cloud-only model.
• Robust Features: SSO, OAuth 2.0, OpenID Connect, and SAML 2.0 rival enterprise solutions.
• Scalable: We scaled Keycloak for a media client’s 50,000 daily users with Kubernetes.
• Community-Driven: 10,000+ GitHub stars ensure constant updates and support.

Stat: 78% of enterprises using open-source IAM like Keycloak report 30-50% cost savings.

Step-by-Step: Set Up Keycloak for a Node.js App

Let’s secure a Node.js app with Keycloak SSO in under an hour.

Step 1: Install Keycloak

Requirements: Java 11+ (OpenJDK), AWS EC2 (us-east-1), optional PostgreSQL.

1. Download Keycloak (26.0.2, May 2025):

wget https://github.com/keycloak/keycloak/releases/download/26.0.2/keycloak-26.0.2.tar.gz
tar -xvzf keycloak-26.0.2.tar.gz
cd keycloak-26.0.2

       2. Start in Dev Mode:

./bin/kc.sh start-dev

Access http://localhost:8080, create an admin user, and secure the password.

Pro Tip: Use PostgreSQL for production to handle 10,000+ users. A client’s dev setup crashed without it.

Step 2: Configure a Realm

A realm is your app’s user and settings container.

1. Create a Realm:
   • In the admin console, click “Create Realm”, name it myapp-realm.
   • Select it from the dropdown.
2. Add a Client:
   • Go to “Clients” > “Create Client”.
   • Set Client ID to myapp-client, Protocol to OpenID Connect, Root URL to http://localhost:3000.
   • Set “Valid Redirect URIs” to http://localhost:3000/callback.

Step 3: Secure Your App

Here’s a Node.js/Express app with Keycloak SSO.

Code: Node.js with Keycloak

const express = require('express');
const session = require('express-session');
const Keycloak = require('keycloak-connect');
const app = express();

const memoryStore = new session.MemoryStore();
app.use(
  session({
    secret: 'hakuna-matata-secure-123',
    resave: false,
    saveUninitialized: true,
    store: memoryStore,
  })
);

const keycloak = new Keycloak({ store: memoryStore }, {
  realm: 'myapp-realm',
  'auth-server-url': 'http://localhost:8080',
  'ssl-required': 'external',
  resource: 'myapp-client',
  'public-client': true,
});

app.use(keycloak.middleware());

app.get('/', keycloak.protect(), (req, res) => {
  res.send(`Welcome, ${req.kauth.grant.access_token.content.preferred_username}!`);
});

app.listen(3000, () => console.log('App running at http://localhost:3000'));

Install Dependencies:

npm install express express-session keycloak-connect

How It Works:

• keycloak-connect redirects unauthenticated users to Keycloak’s login page.
• protect() ensures only logged-in users access the route.
• Use a secure secret to prevent session hijacking.

Pro Tip: Test redirect URIs to avoid 500-error loops. We caught this in a client’s beta test.

Step 4: Customize the Login Page

Brand your login page for a seamless UX.

1. Create a Theme:

     cp -r themes/base/login themes/myapp/login

           Edit themes/myapp/login/login.ftl:

<div class="login-page" style="background-color: #f0f0f0; padding: 20px;">
  <h1>Welcome to MyApp</h1>
  ${kcForm}
</div>

       2. Apply Theme:

            In “Realm Settings” > “Themes”, set “Login Theme” to myapp

Security and Scaling: Pro Tips

Security

With 68% of USA breaches tied to credentials, secure Keycloak like this:

• Short Tokens: Set access token lifespan to 15 minutes in “Realm Settings” > “Tokens”:

{
  "accessTokenLifespan": 900
}

• Prevent XSS: Allow only trusted URLs (e.g., http://localhost:3000) in CORS settings.
• Secure Admin Console: Restrict http://your-server:8080/admin with AWS Security Groups.

Lesson: A California healthcare client failed a HIPAA audit due to loose CORS. We fixed it and passed with zero findings.

Scaling

For high traffic (50,000+ users):

• Kubernetes: Multi-node clusters for redundancy.
• PostgreSQL: Index user tables for 25% faster queries.
• Caching: Infinispan cut latency for a media client.

Stat: 65% of Keycloak users with 10,000+ users need database tuning.

Troubleshooting Common Issues

• Log Splitting: Fix keycloak.log splitting in conf/logback.xml:

<appender name="FILE" class="ch.qos.logback.core.FileAppender">
  <file>keycloak.log</file>
  <append>true</append>
</appender>

• Role Deletion: A client broke logins by deleting a role. Restore from backups and restrict permissions.
