+# Service Clients
+You can use the default constructor, or you can use the system interfaces to construct a service client.
+
+As an example, the following code creates an Amazon DynamoDB client using a specialized client configuration, default credentials provider chain, and default HTTP client factory:
+
+```cpp
+auto limiter = Aws::MakeShared<Aws::Utils::RateLimits::DefaultRateLimiter<>>(ALLOCATION_TAG, 200000);
+
+// Create a client
+ClientConfiguration config;
+config.scheme = Scheme::HTTPS;
+config.connectTimeoutMs = 30000;
+config.requestTimeoutMs = 30000;
+config.readRateLimiter = m_limiter;
+config.writeRateLimiter = m_limiter;
+
+auto client = Aws::MakeShared<DynamoDBClient>(ALLOCATION_TAG, config);
+```
+
+You can also do the following to manually pass credentials:
+`auto client = Aws::MakeShared<DynamoDBClient>(ALLOCATION_TAG, AWSCredentials("access_key_id", "secret_key"), config);`
+
+Or you can do the following to use a custom credentials provider:
+`auto client = Aws::MakeShared<DynamoDBClient>(ALLOCATION_TAG, Aws::MakeShared<CognitoCachingAnonymousCredentialsProvider>(ALLOCATION_TAG, "identityPoolId", "accountId"), config);`
+
+Now you can use your Amazon DynamoDB client.
