+In HCL you can specify the plural `services` key (although not `service`) multiple times:
+
+```hcl
+services {
+  id = "red0"
+  name = "redis"
+  tags = [
+    "primary"
+  ]
+  address = ""
+  port = 6000
+  checks = [
+    {
+      args = ["/bin/check_redis", "-p", "6000"]
+      interval = "5s"
+      timeout = "20s"
+    }
+  ]
+}
+services {
+  id = "red1"
+  name = "redis"
+  tags = [
+    "delayed",
+    "secondary"
+  ]
+  address = ""
+  port = 7000
+  checks = [
+    {
+      args = ["/bin/check_redis", "-p", "7000"]
+      interval = "30s"
+      timeout = "60s"
+    }
+  ]
+}
+```
