110. 3 Approaches…
111. 1. Build new APIs
112. 2. Wrap legacy APIs
113. Read through Copy on Read/Write Dual Writes Replace
114. Data Cruft?
115. 3. Import data with mutations
116. input EliteDailyImport { id: ID name: String url: URL authorID: Int! }
117. Runtime Types Crufty Legacy Data
119. What next?
120. tweetable controversial thoughts
121. containers
122. “Docker who?”
123. What is “serverless”?
124. No one wants Multi-Cloud FaaS
125. FaaS is boring
126. Evented architectures are fun!
127. Serverless Databases
128. Deployment frameworks are boring
129. Architecture frameworks are fun!
